feat: booking confirm modal with cascading Hall → Trainer → Group, linear workflow

- Add confirmed_date, confirmed_group, confirmed_comment to group_bookings (migration #10)
- Linear booking flow: Новая → Связались → Подтвердить (modal) / Отказ
- Confirm modal with cascading selects: Hall → Trainer → Group → Date → Comment
- Groups merged by groupId — shows all days/times (e.g. "СР 20:00, ПТ 16:15")
- Auto-prefill hall/trainer/group from booking's groupInfo via fuzzy scoring
- Proper SHORT_DAYS constant for weekday abbreviations
- Filter chips with status counts, declined sorted to bottom
- "Вернуть" on confirmed/declined returns to "Связались" (not "Новая")

 ## Brand / Styling
-- **Accent**: rose/red (`#e11d48`)
-- **Dark mode**: bg `#0a0a0a`, surface `#171717`
-- **Light mode**: bg `#fafafa`, surface `#ffffff`
-- Logo: transparent PNG, uses `dark:invert` + `unoptimized`
+- **Accent**: gold (`#c9a96e` / `hsl(37, 42%, 61%)`)
+- **Background**: `#050505` – `#0a0a0a` (dark only)
+- **Surface**: `#171717` dark cards
+- Logo: transparent PNG heart with gold glow, uses `unoptimized`
 
 ## Content Data
-- All text lives in `src/data/content.ts` (type-safe, one file to edit)
-- 13 team members with photos, Instagram links, and personal descriptions
+- Primary source: SQLite database (`db/blackheart.db`)
+- Fallback: `src/data/content.ts` (auto-seeds DB on first access)
+- Admin panel edits go to DB, site reads from DB via `getContent()`
+- 12 team members with photos, Instagram links, bios, victories, education
 - 6 class types (Exotic Pole Dance, Pole Dance, Body Plastic, etc.)
+- Master classes with date/time slots and public registration
 - 2 addresses in Minsk, Yandex Maps embed with markers
-- Contact: phone, Instagram
+- Contact: phone, Instagram (no email)
+
+## Admin Panel
+- Password-based auth with HMAC-SHA256 signed JWT (24h TTL)
+- Cookie: `bh-admin-token` (httpOnly, secure in prod)
+- Auto-save with 800ms debounce on all section editors
+- Team members: drag-reorder, photo upload, rich bio (experience, victories, education)
+- Master classes: slots, registration viewer with notification tracking (confirm + reminder), trainer/style autocomplete
+- Group bookings: saved to DB from BookingModal, admin page at `/admin/bookings` with notification toggles
+- Open Day: event settings (date, pricing, discount rules, min bookings), schedule grid (halls × time slots), per-class booking with auto-cancel threshold, public section after Hero
+- Shared `NotifyToggle` component (`src/app/admin/_components/NotifyToggle.tsx`) used across MC registrations, group bookings, and Open Day bookings
+- File upload: whitelisted folders (`team`, `master-classes`, `news`, `classes`), max 5MB, image types only
+
+## Security Notes
+- **CSRF protection**: Double-submit cookie pattern. Login sets `bh-csrf-token` cookie (JS-readable). All admin fetch calls use `adminFetch()` from `src/lib/csrf.ts` which sends the token as `X-CSRF-Token` header. Middleware (`proxy.ts`) validates header matches cookie on POST/PUT/DELETE to `/api/admin/*`. **Always use `adminFetch()` instead of `fetch()` for admin API calls.**
+- File upload validates: MIME type, file extension, whitelisted folder (no path traversal)
+- API routes validate: input types, string lengths, numeric IDs
+- Public MC registration: length-limited but **no rate limiting yet** (add before production)
+
+## Upcoming Features
+- **Rate limiting** on public endpoints (`/api/master-class-register`, `/api/group-booking`, `/api/open-day-register`)
+- **DB backup mechanism** — automated/manual backup of `db/blackheart.db` with rotation
 
 ## AST Index
 - **Always use the AST index** at `memory/ast-index.md` when searching for components, props, hooks, types, or styles
 - Contains: component tree, all exports, props, hooks, client/server status, CSS classes, keyframes
-- Covers all 31 TS/TSX files + 4 CSS files
 - Update the index when adding/removing/renaming files or exports
