 ## Features
 
-- **Public site**: events, booking, contact, community, legal pages, bilingual (EN/ES)
-- **User dashboard**: profile, tickets, payments, sessions/security
-- **Admin** (`/admin`): events, tickets/check-in, users/roles, payments, email templates, media uploads
+- **Public site**: events, booking, contact, community, **photo galleries**, legal pages, bilingual (EN/ES)
+  - Stable `/next` and `/featured` URLs that redirect to the current event
+  - Human-readable event URL slugs (with legacy-ID redirect support)
+- **User dashboard**: overview tab, profile, tickets, payments, sessions/security
+  - Lightning invoice reuse and re-payment straight from the dashboard
+- **Admin** (`/admin`): events, tickets/check-in, users/roles, payments, email templates, media uploads, **photo galleries**
+  - One unified ticket-creation modal with first-class payment status
+- **Payments**: one automatic provider (**Lightning** via LNbits) plus manual providers (**TPago link**, bank transfer, card, cash), all defined in a central provider registry. Manual payments stay pending until an admin reconciles them (they are not auto-failed after the pending TTL).
+- **Photo galleries** (standalone `photo-api` Go service): admins upload event photos, group them into galleries, and share them by visibility mode (public / private / share-link / ticket-holders). See [`photo-api/`](photo-api/README.md).
 - **API**: Swagger UI at `/api-docs`, OpenAPI JSON at `/openapi.json`, health check at `/health`
 
 ## Tech stack
 
 - **Backend**: Node.js + TypeScript, Hono, Drizzle ORM, SQLite (default) or PostgreSQL
-- **Auth**: JWT (via `jose`), **Argon2id** password hashing (with legacy bcrypt verification for older hashes)
+- **Photo service**: standalone Go module (`photo-api/`), its own binary/deploy unit, sharing the backend database and `JWT_SECRET`
+- **Auth**: [Better Auth](https://better-auth.com) — httpOnly cookie sessions (DB-validated on every request for instant revocation), **Argon2id** password hashing (with legacy bcrypt verification for older hashes), magic links, Google sign-in, admin ban/suspend
 - **Email**: `nodemailer` (SMTP) with optional provider config
-- **Frontend**: Next.js 14 (App Router), Tailwind CSS, Heroicons
