Update proxy.ts

Hero gallery: the slideshow on Home doesn’t open full screen. Only portfolio images do, as you asked.
Lightbox: it has no pinch-zoom.
Delete: removing an image still has no confirm step, same as before.
New dependency: drag-and-drop uses @dnd-kit, which I added to package.json.
Touch dragging: I couldn’t test it on a real phone. Mouse and keyboard dragging work.
Health test: src/app/api/health/__tests__/route.test.ts passes, but it prints unhandled rejections. Its prisma mock has no notificationDelivery, so getQueueHealth throws. That comes from the earlier “Remaining features” commit and I left it alone. It’s a quick fix if you want it.

 # NextChair
 
 Booking app as an alternative to Booksy
+
+## VPS deployment (multi-business)
+
+Everything below runs on a fresh VPS with Docker and the Compose plugin
+already installed — no other prerequisite (no host Node.js/npm needed;
+every command either uses Docker itself or plain shell tools). Every code
+block is meant to be pasted as-is, in order.
+
+### 0. One-time: clone the repo and generate your secrets
+
+```bash
+# STACKS_DIR later on must be this exact absolute path — every stack
+# shells `docker compose` back out to the HOST's dockerd via a mounted
+# socket, so the path only resolves to the same thing on both sides if
+# it's cloned here and never moved.
+git clone <your-repo-url> /opt/nextchair
+cd /opt/nextchair
+```
+
+Generate the secrets you'll paste into the `.env` files in the steps
+below. Run these now and keep the output somewhere safe (a password
+manager) — you'll need each value again in a moment.
+
+```bash
+# MYSQL_ROOT_PASSWORD — goes into BOTH stacks/infra/.env and manager/.env
+# (the same value in both places).
+echo "MYSQL_ROOT_PASSWORD=$(openssl rand -hex 24)"
+
+# MANAGER_SESSION_SECRET — manager/.env only.
+echo "MANAGER_SESSION_SECRET=$(openssl rand -hex 32)"
+
+# MANAGER_SETTINGS_ENCRYPTION_KEY — manager/.env only. Encrypts the
+# SMTP/VAPID secrets you'll enter in the Manager's Settings page later.
+# Losing/rotating this makes any already-saved secret there undecryptable,
+# so store it as carefully as the other secrets on this page.
+echo "MANAGER_SETTINGS_ENCRYPTION_KEY=$(openssl rand -hex 32)"
+```
+
+```bash
+# MANAGER_PASSWORD_HASH — manager/.env only. Replace "your-password" with
+# your chosen Manager login password first. Run via a throwaway container
+# so this works with nothing but Docker installed on the host.
+docker run --rm node:22-alpine sh -c \
+  "mkdir -p /tmp/gen && cd /tmp/gen && npm install bcryptjs --no-audit --no-fund >/dev/null 2>&1 && \
+   node -e \"const h=require('/tmp/gen/node_modules/bcryptjs').hashSync('your-password',12); console.log('MANAGER_PASSWORD_HASH=\\\"'+h.replace(/\\$/g,'\\$\\$')+'\\\"')\""
+```
+
+### 1. Shared infrastructure — network, MySQL and Caddy
+
+```bash
+docker network create next-chair-edge
+
+cp .env.infra.example stacks/infra/.env
+```
+
+Edit `stacks/infra/.env`:
+- `MYSQL_ROOT_PASSWORD` — the first secret you generated above.
+- `MYSQL_HOST_PORT` — set this to `127.0.0.1:3306` so MySQL is only exposed on the VPS loopback interface, not publicly. You can still connect to it remotely through an SSH tunnel.
+- `ACME_EMAIL` — a real address you check (Let's Encrypt renewal notices).
+
+```bash
+docker compose -f stacks/infra/compose.yaml --env-file stacks/infra/.env up -d
+```
+
+### 2. Build the shared application image
+
+Every business (and no other step in this guide) runs this same image —
+you only rebuild it here, once, and again whenever you ship a code
+update (see "Updating" below).
+
+```bash
+docker build -t nextchair-app:latest .
+```
+
+### 3. The management UI (Manager)
+
+This is what you'll use to add every business from here on.
+
+```bash
+cp manager/.env.example stacks/manager/.env
+```
+
+Edit `stacks/manager/.env`:
+- `MANAGER_EMAIL` — the email you'll log in with.
+- `MANAGER_PASSWORD_HASH` — the bcrypt hash generated in step 0.
+- `MANAGER_SESSION_SECRET` and `MANAGER_SETTINGS_ENCRYPTION_KEY` — the two
+  other values generated in step 0.
+- `MANAGER_PUBLIC_URL` — `https://` + the domain you'll point at this app
+  in the next step.
+- `MYSQL_ROOT_PASSWORD` — same value as `stacks/infra/.env`.
+- `STACKS_DIR` — same absolute path as step 1.
+
+```bash
+docker compose -f stacks/manager/compose.yaml --env-file stacks/manager/.env up -d --build
+```
+
+Point your chosen Manager domain's DNS (A/AAAA record) at the VPS, then
+give it a Caddy site and reload:
+
+```bash
+cat > stacks/infra/sites/manager.caddy << 'EOF'
+manager.example.com {
+	reverse_proxy next-chair-manager:3000
+}
+EOF
+docker exec next-chair-caddy caddy reload --config /etc/caddy/Caddyfile
+```
+
+(Replace `manager.example.com` with your real domain — Caddy issues its
+TLS certificate automatically on first request.)
+
+### 4. Configure platform-wide settings (once)
+
+Log into the Manager at `https://<your-manager-domain>` and open
+**Settings**. Both sections are optional to fill in now, but doing it
+before adding your first business means that business never needs its
+own SMTP/push setup:
+
+- **Email / SMTP** — your SMTP relay's host/port/username/password and a
+  from-address. Use **Send Test Email** to confirm it before saving for
+  real, then **Save Changes** to apply it to every business.
+- **Push Notifications** — click **Generate VAPID Keys** once (a contact
+  email is enough to start). This is a one-time, platform-wide key pair —
+  see that section's own copy for what happens if you ever regenerate it.
+
+### 5. Add your first business
+
+Still in the Manager: **Add Business** → name, slug, domain. This creates
+its database, generates its secrets, starts its container, and runs its
+migrations for you — no manual per-business `.env` editing needed.
+
+Point that business's own domain's DNS at the VPS (the Manager doesn't do
+this for you), then finish its setup by visiting
+`https://<business-domain>/install`.
+
+Repeat this step for each additional business, whenever you want one.
+
+### 6. Notification delivery (handled by the Manager)
+
+Staff invitation emails, appointment reminders, push notifications,
+loyalty reward emails, WhatsApp-reminder nudges and Google Reviews sync are
+**not sent by the app itself** — it only queues them; something has to
+trigger delivery on a schedule by calling two `CRON_SECRET`-gated
+endpoints (`/api/cron/process-notifications`,
+`/api/cron/sync-google-reviews` — see their route files for the reasoning).
+Without a trigger, every business's queued notifications sit as `PENDING`
+forever, even though the UI says "sent" the moment something is queued.
+
+**The Manager's built-in scheduler does this for you** — nothing to
+install on the host. Once the Manager is running it calls every
+business's notification cron every 30 seconds (adjustable at Settings →
+Monitoring & scheduler, 10 s – 1 hour) and the reviews sync once a day,
+including for businesses added later. That page lists the last run of each
+task per business, so you can confirm it's working.
+
+Each business's `/api/health` also reports whether notifications are
+actually going out (`status: "degraded"` plus the reasons, when the
+processor hasn't run for 10 minutes, deliveries are stuck, or every delivery
+in the last day failed), and the Manager emails you when that happens.
+
+#### Removing the old crontab
+
+If you set up the host crontab from an earlier version of this guide, remove
+it once the Manager scheduler is confirmed working — running both is safe
+(deliveries are claimed one at a time, so nothing is sent twice) but
+pointless:
+
+1. Open Settings → Monitoring & scheduler in the Manager and check that
+   "Process notifications" shows a recent successful run for each business.
+2. On the VPS, as the user that owns `/opt/nextchair`, run `crontab -e` and
+   delete the two `process-cron.sh` lines (notifications and reviews).
+3. Optionally delete `/opt/nextchair/nextchair-cron.log`.
+
+#### Fallback: host crontab
+
+Only if you run with `MANAGER_SCHEDULER_DISABLED=1`, or want an independent
+trigger. [stacks/infra/scripts/process-cron.sh](stacks/infra/scripts/process-cron.sh)
+calls both endpoints for **every** business under `STACKS_DIR` in one run.
+Many minimal VPS images don't ship `cron` — install it first
+(`sudo apt update && sudo apt install -y cron && sudo systemctl enable --now cron`),
+then add this with `crontab -e` as the user that owns `/opt/nextchair`
+(**not** `sudo crontab -e`, so the log file is writable):
+
+```bash
+# Deliver queued notifications every minute (the finest a crontab can do).
+* * * * * STACKS_DIR=/opt/nextchair/stacks /opt/nextchair/stacks/infra/scripts/process-cron.sh notifications >> /opt/nextchair/nextchair-cron.log 2>&1
+
+# Refresh Google Reviews once a day.
+0 3 * * * STACKS_DIR=/opt/nextchair/stacks /opt/nextchair/stacks/infra/scripts/process-cron.sh reviews >> /opt/nextchair/nextchair-cron.log 2>&1
+```
+
+A healthy run logs `<slug> process-notifications ok` for every business. Use
+only one of the two mechanisms at a time as your normal setup.
+
+## Updating after a code change
+
+For an existing NextChair server, **do not re-run the fresh VPS setup above** and do not overwrite your production `.env` files.
+
+First pull the latest code:
+
+```bash
+cd /opt/nextchair
+git pull
+```
+
+Before rebuilding, check whether either example environment file has gained new settings since your last deployment:
+
+```bash
+# Review only — do not copy these files over your existing production .env files.
+diff -u stacks/infra/.env .env.infra.example || true
+diff -u stacks/manager/.env manager/.env.example || true
+```
+
+If a new variable has been added, copy **only that variable** into the corresponding production `.env` and give it an appropriate value. Keep all existing passwords, secrets and generated values unchanged.
+
+Then rebuild the one shared image every business uses:
+
+```bash
+cd /opt/nextchair
+docker build -t nextchair-app:latest .
+```
+
+Then, for **each** business: use its **Update** button in the Manager UI,
+or run this directly:
+
+```bash
+cd /opt/nextchair/stacks/<slug>
+docker compose --env-file .env up -d --force-recreate
+```
+
+Either way this recreates that business's container against the freshly
+built image — and its own startup automatically runs
+`prisma migrate deploy`, so any new database migration is applied on the
+same step. No separate migration command needed.
+
+If the code change touched the **Manager app itself** (anything under
+`manager/`), rebuild/recreate the Manager too:
+
+```bash
+cd /opt/nextchair
+docker compose -f stacks/manager/compose.yaml --env-file stacks/manager/.env up -d --build
+```
+
+If both the business app and Manager changed, do both update steps.
+
+## Upgrading from a version that included Dockge (one-time)
+
+Dockge used to run alongside NextChair Manager as a separate stack
+management UI. It's no longer part of the shared infrastructure stack —
+Manager is the only tool needed to provision and manage business stacks,
+so the two were redundant. If your server was set up before this change,
+existing tenant databases, tenant containers, business Compose files, and
+the global SMTP/VAPID settings are all unaffected — this only removes the
+old Dockge container.
+
+Pull the change, then re-apply the infra stack with `--remove-orphans` so
+Docker removes the container that's no longer defined in
+`stacks/infra/compose.yaml`:
+
+```bash
+cd /opt/nextchair
+git pull
+
+docker compose \
+  -f stacks/infra/compose.yaml \
+  --env-file stacks/infra/.env \
+  up -d --remove-orphans
+```
+
+`--remove-orphans` only removes containers Compose no longer recognizes
+(the old `next-chair-dockge` container) — it does not touch Caddy, MySQL,
+or their volumes.
+
+This does **not** delete Dockge's own data volume
+(`next-chair-dockge-data`) — Docker never removes volumes on its own, and
+this command has no reason to either. Once you've confirmed Caddy, MySQL
+and every business are still healthy, you can remove that now-unused
+volume by hand:
+
+```bash
+docker volume rm next-chair-dockge-data
+```
+
+Finally, `STACKS_DIR` and `DOCKGE_HOST_PORT` in `stacks/infra/.env` were
+only ever used by Dockge and are safe to delete from that file — nothing
+else in the infra stack reads them. (Manager keeps its own separate
+`STACKS_DIR` in `stacks/manager/.env`; leave that one alone.)

+# Calendar
+
+A living reference for the day calendar on `/staff` (a barber's own day) and
+`/owner/calendar` (everyone, one column per barber). Both render
+`src/features/staff/components/day-calendar.tsx`.
+
+## What it's built on
+
+[react-big-calendar](https://github.com/jquense/react-big-calendar) (MIT) with
+its drag-and-drop addon, restyled to match the app in `day-calendar.css`
+(scoped under `.day-cal`). It was chosen over DayPilot Lite mainly because
+per-barber columns, a current-time line and sideways scrolling on a phone all
+work out of the box; FullCalendar and Schedule-X put per-resource columns
+behind a paid licence.
+
+Only the day view is used. The agenda (list) view is a separate component.
+
+## Time zones — read this before touching it
+
+The library works in JavaScript `Date`s, which carry the **browser's** time
+zone; the app's scheduling data is **business-local minutes since midnight on
+a business-local date**. So the calendar never sees a real instant: times go in
+as "floating" dates (minutes laid onto one fixed day — `calendar-time.ts`) and
+a drop comes back out as plain minutes. The real date and the business time
+zone are applied on the server in `moveCalendarAppointmentAction`.
+
+## Drag to reschedule
+
+Turned on per page with the `reschedule` prop (`"owner"` or `"staff"`).
+
+- A drop **never saves on its own.** It opens a confirmation ("From 11:00 AM
+  with Leo → To 1:00 PM with Leo… the customer will be notified"), because a
+  reschedule emails the customer.
+- `"owner"`: any appointment in the business, and it can be dropped into
+  another barber's column (a reassignment). `"staff"`: their own bookings, along
+  the time axis only.
+- Only `pending_approval`, `confirmed` and `arrived` bookings can be moved —
+  the same statuses `rescheduleBooking` accepts. Breaks, time off, and finished
+  or in-progress bookings are not draggable. Resizing (changing the length) is
+  off: duration comes from the services.
+- **The server is the gate.** `moveCalendarAppointmentAction` delegates to the
+  existing `ownerRescheduleAppointmentAction` / `rescheduleStaffAppointmentAction`,
+  so working hours, breaks, overlaps, the staff member's services, the business's
+  minimum-notice rule, the audit log, notifications, reminders and Google
+  Calendar sync all behave exactly as they do from the appointment screen. A
+  rejected move shows the reason inside the dialog and nothing is saved.
+- The calendar itself does not stop you dropping onto a break or outside
+  someone's hours — it just fails the server check.
+
+## Phones
+
+Columns keep a 190px minimum and the grid scrolls sideways, with the hour
+labels pinned on the left and the header row scrolling with it. Dragging was
+verified with a mouse only; the library has touch handlers but this has not been
+tried on a real touch screen. The appointment screen's Reschedule always works.

+# Notifications reference
+
+A living reference for every notification NextChair sends — what it is,
+who gets it, on which channels, and whether the recipient can turn it
+off. Unlike the other files in `docs/` (dated phase summaries), this one
+is meant to be kept current as notifications change; if you add, remove,
+or retarget one, update this file in the same change.
+
+## Two separate mechanisms
+
+Most of what's on this page goes through the **queued notification
+system**: an event happens, a `Notification` + one `NotificationDelivery`
+row per applicable channel is created immediately, but the actual
+EMAIL/PUSH send only happens when the background processor runs (see
+`src/services/notifications/reminder-worker.ts`, triggered by
+`POST /api/cron/process-notifications` — see the root README's
+"Notification delivery" section for how that's scheduled on a real
+deployment). `IN_APP` deliveries have no send step; they're just a
+database row the notification bell/centre reads directly.
+
+**One-time codes** (below, in their own section) are different — they're
+sent synchronously, the moment they're requested, with no queue at all.
+
+Either way, nothing actually reaches an inbox unless that business has
+`EMAIL_PROVIDER=brevo` configured (Manager's Settings → Email, or a
+business's own `.env`) — with the default `EMAIL_PROVIDER=console`,
+every send just logs to the container's console instead.
+
+## Channels
+
+- **EMAIL** — sent only if the recipient has a resolvable email address
+  (a registered user's `User.email`, or a guest customer's
+  `CustomerProfile.email`).
+- **PUSH** — sent only if the recipient has at least one active (not
+  revoked) browser push subscription.
+- **IN_APP** — only meaningful for a recipient with a real account
+  (`recipientUserId` set) — a guest customer never gets one, since they
+  have nothing to sign into.
+
+## Preferences — who can turn what off, and what's on by default
+
+See `src/services/notifications/types.ts`'s `PREFERENCE_CONTROLLED_TYPES`
+— this is the single source of truth for which types have a toggle at
+all; everything not listed there is **required** (always sent on every
+channel it has a valid target for, no toggle anywhere — see "Fixed
+no-email types" below for a separate, smaller mechanism that trims one
+channel off a handful of these without making them toggleable).
+
+- **Customer-facing**: only `BOOKING_REMINDER` is optional (and only
+  controls the customer reminder — see "Reminder timing"). Everything else
+  (confirmations, changes, cancellations, loyalty) always notifies the
+  customer on every resolvable channel — not finding out your
+  appointment was cancelled is a real risk, not just noise.
+- **Staff- and owner-facing**: every type is optional. The owner of a
+  business is commonly also its only barber — one `StaffProfile`, one
+  account — so without this, a single new booking would unconditionally
+  notify that one person twice (`STAFF_NEW_APPOINTMENT` +
+  `OWNER_NEW_BOOKING`) on every channel, including in-app, with no way to
+  quiet either copy. (Cross-role dedup, below, now also prevents the
+  literal duplicate even when both happen to be enabled.)
+
+Toggles live at **Settings → Notifications** — customers see one
+"Appointment reminders" group; staff see their own six groups, plus five
+more owner-only groups if they hold `VIEW_REPORTING` (i.e. are actually
+an owner — see `src/services/notifications/recipients.ts`'s
+`getOwnerUserIds`, which checks the same permission).
+
+**Defaults**: `types.ts`'s `defaultPreferenceIsEnabled(type)` is the
+single source of truth for what a toggle shows/does before anyone has
+ever saved a preference row for it — used both by the actual send
+decision (`notification.service.ts`'s `isChannelEnabled`) and by the
+Settings pages themselves, so a toggle's initial on/off state always
+matches what will actually happen. Once a user explicitly saves a
+preference, that stored value always wins, in either direction — this
+function only governs the "nobody has touched this yet" fallback.
+
+Most staff/owner types default to **on**. These default to **off**
+(on every channel)
+instead — a solo owner-barber otherwise gets emailed/pushed/in-app'd for
+everything the moment they sign in, with no gentle on-ramp:
+
+| Type | Why |
+|---|---|
+| `STAFF_NEW_APPOINTMENT` | Noisy for a busy barber; `STAFF_APPOINTMENT_CANCELLED` (which stays on) is the one that actually needs acting on. |
+| `STAFF_APPOINTMENT_RESCHEDULED` | Same reasoning. |
+| `OWNER_NEW_BOOKING` | Same as STAFF_NEW_APPOINTMENT, from the owner's side. |
+| `OWNER_NO_SHOW` | The barber who marked it already knows — there's no staff-facing equivalent by design. |
+
+Defaults can also differ **per channel**, not just per type
+(`DEFAULT_DISABLED_CHANNELS` in `types.ts`). Currently one:
+`STAFF_APPOINTMENT_REMINDER` is **on** for push and in-app but **off** for
+email — a barber gets a nudge on their phone two hours out without a second
+email for something that's about to happen anyway. Email is opt-in under
+Settings → Notifications.
+
+## Fixed no-email types
+
+A few types are `EMAIL` never, always, and unconditionally — not a
+default that can be toggled back on, because the type either has no
+preference toggle at all or (for `BOOKING_BARBER_CHANGED`) the decision
+is per-booking context a stored preference can't express. This is
+`NotifyParams.skipEmail` in `notification.service.ts` — a single boolean
+the caller passes, checked in `resolveChannels()`'s EMAIL branch
+independently of the preference system. PUSH/IN_APP are unaffected in
+every case below.
+
+| Type | Condition |
+|---|---|
+| `BOOKING_COMPLETED` | Always — a "thanks for visiting" email after every single cut was more noise than value. |
+| `LOYALTY_STAMP_ADDED` | Always — a stamp is added on nearly every visit. |
+| `LOYALTY_REWARD_REDEEMED` | Always — the customer is present when a reward is redeemed; an email receipt afterward added little. |
+| `BOOKING_BARBER_CHANGED` | Only when the customer originally booked without picking a specific staff member ("any available barber" — see `Appointment.staffSelectedByCustomer`) and hasn't been reassigned before. Someone who booked "any available" is less likely to care who they end up with; someone who picked this barber specifically still gets emailed. |
+
+## Cross-role deduplication
+
+A person who holds two roles for the same booking (most commonly a solo
+owner-barber: one `User`, one `StaffProfile`, and a role with
+`VIEW_REPORTING`) can be the target of two *equivalent* notifications for
+one underlying event — e.g. a new booking fires both
+`STAFF_NEW_APPOINTMENT` (they're the assigned staff) and
+`OWNER_NEW_BOOKING` (they're also an owner). Since both resolve to the
+identical `recipientUserId`, `notification.service.ts`'s `notify()`
+detects this and suppresses the less-specific one — on every channel,
+not just email — rather than relying on the person to manually mute one
+side.
+
+`EQUIVALENCE_GROUPS` in that file lists which types are considered the
+same underlying event, and their relative priority:
+
+| Group | Types (higher priority first) |
+|---|---|
+| `new_appointment` | `STAFF_NEW_APPOINTMENT` > `OWNER_NEW_BOOKING` |
+| `appointment_cancelled` | `STAFF_APPOINTMENT_CANCELLED` > `OWNER_BOOKING_CANCELLED` |
+
+When an equivalent, higher-or-equal-priority notification already exists
+for the same `(businessId, appointmentId, recipientUserId)`, the new one
+is still created as a `Notification` row (audit trail, keeps
+`idempotencyKey` semantics intact) but with **zero** deliveries — nothing
+sends on any channel. This relies on call order: every real call site
+(`booking-notifications.ts`) already notifies the STAFF_* type before
+looping the OWNER_* type for the same event, so the more specific one is
+always created first. Only types explicitly listed in
+`EQUIVALENCE_GROUPS` ever participate — e.g. `OWNER_NO_SHOW` has no staff
+equivalent and is never touched by this, and any future owner-only
+*actionable* type (e.g. "approve this booking") would likewise stay
+untouched simply by not being added to the map. Unrelated events for the
+same appointment (a confirmation, then later a cancellation) are never
+conflated — they're different types in different groups, or no group at
+all.
+
+## Reminder timing
+
+`src/services/scheduling/reminder-scheduling.ts` schedules reminders at
+fixed offsets before the appointment, independently for the customer and
+the assigned staff member:
+
+- **Customer** (`BOOKING_REMINDER`): one reminder, **24 hours** before. If
+  the booking was made too late for that (a same-day or next-morning
+  booking), they get one **2 hours** before instead — never both, and never
+  nothing, unless the appointment is under 2 hours away.
+- **Staff** (`STAFF_APPOINTMENT_REMINDER`): one reminder, **2 hours**
+  before. No 24-hour one. Push and in-app on by default, email opt-in —
+  see "Defaults" above.
+- **Owner**: no reminders.
+
+A reminder time that's already in the past when the booking is
+made/approved is never scheduled retroactively.
+
+**In-app reminders are held back until they're due.** Every scheduled
+notification's in-app copy is created `SCHEDULED`, not `SENT`, so it stays
+out of the notification bell and unread count until the background
+processor releases it at the reminder time (`releaseDueInAppReminders` in
+`reminder-worker.ts`). Cancelling or rescheduling cancels it along with the
+email/push copies, so a stale reminder never appears.
+
+**Stale-send guard.** Before sending (or releasing) a reminder, the worker
+checks the appointment is still `CONFIRMED` and hasn't started; if not, the
+delivery is marked `CANCELLED` (not `FAILED`, so it doesn't count toward the
+owner's delivery-failure alert). This is a backstop for the processor being
+down long enough that a "24 hours before" reminder would otherwise arrive
+after the appointment.
+
+**Guest links.** A guest has no account, so every customer-facing link in
+their emails carries an access token (`customerAppointmentLink` in
+`guest-access.service.ts`). The booking-time token is random and only its
+hash is stored, so later emails use a token *derived* from the appointment
+id and `AUTH_SECRET` instead; `validateGuestAccessToken` accepts either, and
+revoking a guest appointment's access kills both.

+## Customer-facing
+
+| Type | Fires when | Default subject | Email |
+|---|---|---|---|
+| `BOOKING_CONFIRMED` | A new booking is created and doesn't need approval | "Booking confirmed" | Always |
+| `BOOKING_PENDING_APPROVAL` | A new booking is created but the business requires approval first | "Booking request received" | Always |
+| `BOOKING_APPROVED` | An owner approves a pending booking | "Booking approved" | Always |
+| `BOOKING_RESCHEDULED` | The appointment's time changes (including an owner reassigning staff, which also triggers a reschedule) | "Booking rescheduled" | Always |
+| `BOOKING_CANCELLED` | The appointment is cancelled, by anyone | "Booking cancelled" (carries a "This was a late cancellation." note when applicable — not a separate type) | Always |
+| `BOOKING_BARBER_CHANGED` | An owner reassigns the appointment to a different staff member | "Your barber has changed" | Only if the customer originally picked a specific staff member — see "Fixed no-email types" |
+| `BOOKING_COMPLETED` | The appointment is marked completed | "Thanks for visiting" | Never |
+| `BOOKING_REMINDER` *(optional)* | 24 hours before a confirmed appointment (2 hours before if booked with less than 24 hours' notice) | "Upcoming appointment reminder" | Default on |
+| `LOYALTY_STAMP_ADDED` | A loyalty stamp is added to their card | "You've earned a loyalty stamp" | Never |
+| `LOYALTY_REWARD_EARNED` | Their stamp count reaches the reward threshold | "You've earned a reward" | Always |
+| `LOYALTY_REWARD_EXPIRING` | A reward's expiry is within 7 days — sent once when it enters that window, and once more when it's down to its last day (two at most per reward) | "Your reward is expiring soon" | Always |
+| `LOYALTY_REWARD_REDEEMED` | Their reward is applied to an appointment | "Reward applied" | Never |
+
+## Staff-facing
+
+| Type | Fires when | Default subject | Default |
+|---|---|---|---|
+| `STAFF_NEW_APPOINTMENT` *(optional)* | A new appointment is booked with them | "New appointment" | Off |
+| `STAFF_APPOINTMENT_RESCHEDULED` *(optional)* | One of their appointments is rescheduled | "Appointment rescheduled" | Off |
+| `STAFF_APPOINTMENT_CANCELLED` *(optional)* | One of their appointments is cancelled | "Appointment cancelled" | On |
+| `STAFF_APPOINTMENT_REMINDER` *(optional)* | 2 hours before their appointment | "Upcoming appointment reminder" | In-app and push on, email off |
+| `STAFF_SCHEDULE_CHANGED` *(optional)* | An **owner** edits their working hours/breaks/time-off on their behalf — never fires from the self-service editors, since notifying someone about their own edit would just be noise | "Your schedule was updated" | On |
+| `STAFF_INVITATION_RECEIVED` *(optional)* | They're added as a new team member | "You've been invited to join `{business}`" | On |
+| `STAFF_APPOINTMENT_CHECKED_IN` | Defined in the schema, has a recipient assigned — **but nothing in the codebase currently triggers it.** Preference-controlled for forward-compatibility, but has no toggle in the UI since there's nothing to preview. Left dormant on purpose | — | — |
+
+## Owner-facing
+
+Sent to *every* active staff member whose role holds `VIEW_REPORTING` —
+that can be more than one person; there's no single "the owner" column
+anywhere in the schema.
+
+| Type | Fires when | Default subject | Default |
+|---|---|---|---|
+| `OWNER_NEW_BOOKING` *(optional)* | A new booking is made anywhere in the business | "New booking" | Off |
+| `OWNER_BOOKING_CANCELLED` *(optional)* | A booking is cancelled anywhere in the business | "Booking cancelled" | On |
+| `OWNER_NO_SHOW` *(optional)* | A customer is marked as a no-show (staff-facing equivalent doesn't exist — the barber who marked it already knows) | "No-show recorded" | Off |
+| `OWNER_STAFF_INVITATION_ACCEPTED` *(optional)* | An invited staff member verifies their email and joins | "Invitation accepted" | On |
+| `OWNER_REPEATED_DELIVERY_FAILURE` *(optional)* | The background processor itself detects repeated delivery failures that day — a self-monitoring alert, not triggered by a domain event. At most once per business per day | "Some notifications failed to send" | On |
+

 3. A guest is never matched against a registered customer's profile, even on an exact email match — that would attach a guest's booking to a real account without verification.
 4. No match → a new guest profile is created. Existing-profile fields are never overwritten on a match.
-5. **Guest appointment access is "order tracking" by unguessable id**, not by verified identity — no magic-link/OTP system was built this phase. This is a deliberate, documented scope limitation (see §12), not an oversight.
+5. ~~**Guest appointment access is "order tracking" by unguessable id**, not by verified identity~~ — *superseded in Phase 7.* A guest appointment now needs a single-purpose access token in the link (`?token=…`), checked by `assertCanAccessAppointment` against `GuestAppointmentAccessToken` (see `src/services/scheduling/guest-access.service.ts` and `docs/notifications.md`). The appointment id alone is rejected; the page returns "not found" and the actions refuse. This is covered by `src/services/scheduling/__tests__/guest-access.integration.test.ts` ("an appointment id alone is rejected"). What was originally described here — no magic-link/OTP flow in Phase 4 — is still true of the phase as shipped.
 
 ## 8. Security / ownership rules
 
@@ -117,11 +117,11 @@ Found and fixed while verifying, not left in place:
 - **A silent test-cleanup leak** in the Phase 3 integration fixtures: `cleanupTestBusiness` tried to delete the test `Business` first, but `Appointment.staff` is `onDelete: Restrict` (a deliberate production safeguard), which blocked the cascade to `StaffProfile` for any test that had actually booked something — the failure was swallowed by a bare `.catch(() => {})`. This had been silently leaking a "Test Barbershop" row per affected test run since Phase 3; it only surfaced now because a manual verification pass queried `getPrimaryBusiness()` against a database that had just run the integration suite and picked up a leaked row instead of the real seed. Fixed by deleting the business's appointments before the business itself.
 - **Desktop layout was effectively unstyled for the "browsing" screens** (Home, Appointments, Settings, and the bottom nav) — content simply didn't reflow or cap its width above mobile size, leaving a large empty right-hand column rather than anything intentional. Applied a **baseline** fix (a centered `max-w-2xl` content column, matching the pattern the booking flow's individual steps already used) across Home, Appointments, Settings, the shared `BottomNav`, `BarberDateTimePicker`, and `DetailsForm`. **This is not a full desktop redesign** — no side-by-side / grid layouts were built for browsing screens, only a consistent centered treatment so nothing looks broken. A genuine desktop-specific layout (e.g. a wider services grid, a split-pane appointment list) is a reasonable Phase 5+ item if desktop usage turns out to matter.
 - **Reschedule's route was moved out of the `(customer)` route group** (`(customer)/appointments/[id]/reschedule` → top-level `appointments/[id]/reschedule`) after discovering the shared picker's own fixed bottom action bar was being covered by the persistent bottom nav on that route, blocking the "Confirm Reschedule" button. Matches the same reasoning `/book`'s layout already documents.
-- **Guest appointment access remains order-tracking-by-id only** (§7, point 5) — not a bug, but worth restating as the clearest remaining security-adjacent scope boundary: a guest with the appointment id can view/reschedule/cancel it without further verification. Fine for this phase's threat model (ids are unguessable `cuid`s, never enumerable), but a real magic-link/OTP flow would close this gap properly.
+- ~~**Guest appointment access remains order-tracking-by-id only**~~ — *closed in Phase 7.* A guest with only the appointment id can no longer view, reschedule, cancel or export the booking; they need the token from their confirmation page or email link (§7, point 5). Still open and deliberate: the token is a bearer link (anyone holding it has access until it expires, 90 days after the appointment ends) rather than a verified identity such as an OTP.
 
 ## 13. Before Phase 5
 
-- Decide whether guest-booking access needs stronger verification (magic link / OTP) before this becomes a compliance concern, or whether "unguessable id" remains acceptable for the foreseeable future.
+- ~~Decide whether guest-booking access needs stronger verification~~ — answered in Phase 7 with per-appointment access tokens; a magic-link/OTP step on top remains optional.
 - If desktop usage is expected to matter, budget real design time for Home/Appointments rather than the baseline centering applied here.
 - The `e2e/` suite and `test:integration` script both assume a disposable Postgres the caller provides — there's no CI wiring yet to spin one up automatically; that's worth doing before this becomes the main safety net.
 - Loyalty UI, staff/owner-facing screens, notifications, and payments are all still untouched, exactly as scoped.

 ## 19. Known limitations
 
-- **Working-hours editing has no conflict detection**, on both the self-service (Phase 5) and owner-on-behalf-of-staff (this phase) editors — unlike breaks, time off, business hours, staff deactivation, and service-eligibility removal, all of which do. A pre-existing Phase 5 gap this phase chose not to retroactively fix, given the size of the remaining Phase 6 scope; flagged again here rather than silently carried forward.
+- **Working-hours editing had no conflict detection** (both the self-service and owner-on-behalf editors) — **closed in Phase 7** ("Working-hours conflict review": `findWorkingHoursConflicts` / `setWorkingHours({ acknowledgeConflicts })` in `staff.service.ts`, the conflict list in `working-hours-form.tsx`, covered by `staff.service.integration.test.ts`). Kept here only as history.
-- **Owner-editable breaks/whole-day time off for a staff member were not built** — only partial-day "Block Time" (via `OwnerBlockTimeButton`) satisfies "add time off on behalf of staff" this phase; a staff member's own recurring breaks and whole-day time off can currently only be edited by that staff member themselves.
+- **~~Owner-editable breaks/whole-day time off for a staff member were not built~~** — *resolved.* Owner-on-behalf-of editing of a staff member's breaks and whole-day time off was built in Phase 7 (Manage → Team → staff → Breaks / Time Off). The one remaining piece, editing and deleting partial-day "Block Time" entries (which `OwnerBlockTimeButton` creates), now also works: they are listed on the same Time Off page, for the owner (`MANAGE_STAFF`) and for staff on their own Time Off settings page, using the same update/delete actions and conflict review.
 - **Staff service eligibility is edited only from the Staff Detail page**, not duplicated on the Services & Categories page (the brief mentions "assign eligible staff" under Services too) — one edit surface, avoiding two places that could drift out of sync.
-- **"Requires staff approval to redeem" is informational text only** in the loyalty config UI — redemption is already gated behind the `MANAGE_LOYALTY_STAMPS` permission and there is no customer-initiated redemption request to approve against, so no separate approval-queue workflow exists.
+- **"Requires staff approval to redeem" and "Apply reward automatically" were removed from the loyalty settings form** — neither did anything (redemption is always staff-initiated and gated by `MANAGE_LOYALTY_STAMPS`). The two `LoyaltyProgramme` columns still exist, unused.
 - **A repeated run of the E2E suite against the same (non-reseeded) database is not fully idempotent**: journey 10 (redeem reward) consumes the seed's one AVAILABLE reward, and one seed appointment (`appt-today-checkedin`, timed via `minutesFromNow` to reliably exercise `selectCurrentAppointment`'s CHECKED_IN tier) can occasionally start a few minutes before the business's 10:00 opening depending on exactly when the seed happens to run, which the opening-hours conflict test now handles defensively rather than assuming a clean save — this is a real, if narrow, characteristic of time-relative seed fixtures re-run without a fresh database, same category of issue Phase 5's own summary flagged (§13 there); it does **not** affect a single authoritative run against a freshly seeded database, which is how CI should always run it.
 - **Notification delivery, payments, deposits, advanced financial reporting, payroll, multi-business/multi-location, PWA, and offline** remain entirely out of scope, per the brief's own boundary.
 
 ## 20. Review items for Phase 7
 
-- Decide whether owner-editable breaks and whole-day time off (on behalf of staff) should be built, or whether "Block Time" (partial-day) remains the only owner-side lever indefinitely.
+- ~~Decide whether owner-editable breaks and whole-day time off (on behalf of staff) should be built~~ — built in Phase 7; Block Time edit/delete followed later (see §19).
 - Decide whether working-hours edits (both self-service and owner-on-behalf-of) should gain the same conflict-review treatment as breaks/time-off/business-hours, closing the gap flagged in §19.
 - Real notification delivery (email/SMS/push) is still entirely unbuilt — both the Phase 5 preference grid and this phase's invite-link workaround are waiting on it.
 - Payments/deposits and any real financial reporting beyond the operational dashboard estimate are unstarted; `Appointment.discountAmount` exists and is populated correctly, but nothing yet reconciles it against an actual payment.

+# NextChair Manager
+
+Standalone platform-operator tool for provisioning and managing NextChair
+business deployments on the shared multi-business VPS setup (see
+`../stacks/`). Not part of the main app — a genuinely separate Next.js
+app, own `package.json`, own build, own container.
+
+## Why it's a separate app
+
+An earlier attempt at this exact feature was built as routes inside the
+main app (`src/app/manager/...`). It was reverted after repeated,
+never-fully-resolved bugs: the main app's `src/proxy.ts`, root layout,
+root page, and global `SessionProvider` all statically import Prisma /
+Auth.js / business branding — code a Manager (which has no business
+database of its own, by definition) kept transitively pulling in, causing
+crashes in "Manager mode."
+
+This app avoids that class of bug structurally rather than by careful
+avoidance: it never imports anything from the main app's `src/` at all.
+A few small pieces (bcrypt convention, the signed-cookie primitive) were
+copied and adapted, not imported — see `src/lib/auth.ts` and
+`src/lib/session.ts`.
+
+## What it does
+
+- Lists provisioned businesses and their running/stopped state.
+- **Add Business**: collects a name/slug/domain, then generates secrets,
+  creates that business's database + user on the shared MySQL server,
+  writes its `stacks/<slug>/compose.yaml` + `.env` + Caddy site file,
+  reloads Caddy, starts the container, and runs its migrations. See
+  `src/lib/provisioning.ts` for the exact sequence.
+- Per business: start / stop / restart / update (recreate the container
+  against the current shared image tag — not a source rebuild, and run as
+  a background job with live progress and an optional "back up first") /
+  view recent logs.
+- Does **not** duplicate the `/install` wizard — after provisioning, the
+  operator is linked to `https://<domain>/install` to finish that
+  business's own setup.
+
+## Scheduler, jobs, backups and alerts
+
+All of this runs inside the Manager process — no host crontab, no extra
+service. State lives next to `global-settings.json`, under
+`STACKS_DIR/manager/` (and `STACKS_DIR/backups/`), so it survives rebuilds.
+
+- **Scheduler** (`src/instrumentation.ts` → `src/lib/scheduler*.ts`): one
+  guarded interval, a task registry with per-task intervals and
+  per-business overlap guards, last-run results in `scheduler-state.json`
+  (shown at Settings → Monitoring & scheduler). Tasks: notification cron
+  (`POST /api/cron/process-notifications` with each stack's `CRON_SECRET`,
+  every 30 s by default), daily Google reviews sync, health checks (every
+  3 min by default), scheduled backups, hourly housekeeping, and an
+  optional external heartbeat (`MANAGER_HEARTBEAT_URL`). Turn it off with
+  `MANAGER_SCHEDULER_DISABLED=1`.
+  **Fallback:** `stacks/infra/scripts/process-cron.sh` (host crontab) still
+  works and does the same notification/reviews calls — use it only if the
+  scheduler is disabled, never both.
+- **Jobs** (`src/lib/jobs.ts`, `locks.ts`): Update, Backup, Restore and
+  Delete run as background jobs writing `manager/jobs/<id>.json` (status,
+  steps, log tail); the UI polls `GET /api/jobs/<id>`. Each holds a
+  per-business lock (`manager/locks/<slug>.json`) so they can't overlap.
+  A lock whose heartbeat is older than 2 minutes is stale and may be taken
+  over; on boot, jobs left "running" are marked failed and their locks
+  released.
+- **Backups** (`src/lib/backup*.ts`, `restore.ts`; UI at a business's
+  *Backups* page and the global *Restore* page): a plain `.7z`
+  (`7zz`, **not password-protected**) of the database dump, media and
+  config, in `STACKS_DIR/backups/<slug>/`. Written as `.partial`, verified
+  with `7zz t`, then renamed; the newest N (default 2, per business) are
+  kept. Safety backups (before an update or a replacing restore) and final
+  backups (before a delete) are kept separately and never evict them.
+  Because there is no password, an archive holds the business's secrets in
+  the clear (its `.env`: database password, auth secret, SMTP password,
+  VAPID private key) — files are written owner-only (0600) and the
+  download route is behind the Manager login; keep any downloaded copy as
+  private as the server itself. Restore works onto an existing business (after a safety backup) or a server that
+  never had it; see `RESTORE_STEPS` in `src/lib/restore.ts`. A backup
+  whose last migration is newer than the app image's is refused.
+- **Alerts** (`src/lib/health-watcher.ts`): per-business ok / degraded /
+  down. Two consecutive bad checks before the first email; emails on
+  change and on recovery, and a daily reminder while still bad. Set the
+  operator address and toggles at Settings → Monitoring & scheduler (uses
+  the Email settings' SMTP). Businesses stopped from the Manager, or mid
+  update/backup/restore, are not probed. An external check is still needed
+  for "the whole VPS is down" — use `MANAGER_HEARTBEAT_URL`.
+
+## How auth works
+
+A single dedicated platform-operator credential (`MANAGER_EMAIL` /
+`MANAGER_PASSWORD_HASH`, bcrypt cost 12) — not tied to any one business's
+own Super Administrator, since this tool spans every business's separate
+database and has no "primary" one of its own. A signed (HMAC, not
+encrypted) cookie holds the session; see `src/lib/session.ts`.
+
+## The Docker-socket trust boundary
+
+This container has the host's Docker socket mounted (`docker.sock`) so it
+can run `docker compose`/`docker exec` against the host's dockerd — see
+`src/lib/docker.ts`. Root inside this container plus that socket
+effectively means root on the host. Consequences:
+
+- It must stay behind the login above at all times — never expose it
+  without that gate, and don't reuse `MANAGER_PASSWORD_HASH` anywhere
+  else.
+- `STACKS_DIR` must be bind-mounted at the *identical absolute path* on
+  both host and container (see `.env.example`) — a `docker compose -f
+  <path>` command run from inside this container is executed by the
+  *host's* dockerd, so the path only means the same file on both sides if
+  the mount doesn't change it.
+
+## Setup
+
+```bash
+cp manager/.env.example stacks/manager/.env   # fill in real values
+docker compose -f stacks/manager/compose.yaml --env-file stacks/manager/.env up -d --build
+```
+
+Requires `stacks/infra/compose.yaml` already running (shared MySQL,
+Caddy, the `next-chair-edge` network). Add a Caddy site for this app the
+same way as any business (see `stacks/infra/sites/.gitkeep`), pointed at
+`next-chair-manager:3000`.
+
+## Local development
+
+```bash
+cd manager
+npm install
+cp .env.example .env.local
+npm run dev
+```
+
+Requires network access to a real MySQL server and `docker`/`docker
+compose` on the machine you run it from for the provisioning/stack
+actions to actually work — the dashboard's read-only parts (listing
+stacks) will also just show nothing if `STACKS_DIR` doesn't point at a
+real directory yet.

+ *
+ * No `<Modal>` here — Manager has no shared dialog primitive (no UI kit
+ * at all, by design; see edit-business-form.tsx's plain-HTML convention).
+ * The overwrite-protection ask is met with an inline warning panel
