+# 11 — Public Guest Gallery
+
+Purpose
+- Provide a shareable, mobile-friendly gallery for guests who only need to view and download approved photos.
+- Respect existing join-token security and automatically disable access once a package’s gallery duration expires.
+
+Access Model
+- URL pattern: `https://<app-domain>/g/{joinToken}`. Tokens are the same join tokens tenants already issue; revoking or expiring a token immediately locks the gallery.
+- Tokens expire when the associated event package’s `gallery_expires_at` passes; guests receive an explanatory message (HTTP `410`).
+- Only *approved* photos appear; pending/rejected items remain hidden.
+
+Client Experience
+- Responsive grid with lazy-loaded thumbnails (IntersectionObserver) and infinite scroll/pagination.
+- Event branding colours (primary, secondary, background) are applied via CSS custom properties fetched from the API.
+- Fullscreen lightbox shows creation timestamp + guest label when available and exposes a single-photo download button (streams the original asset).
+
+API Touchpoints (see 03 — API Contract for details)
+- `GET /api/v1/gallery/{token}` → event snapshot + branding.
+- `GET /api/v1/gallery/{token}/photos` → cursor-based pagination of approved photos.
+- `GET /api/v1/gallery/{token}/photos/{photo}/download` → single-photo download/redirect.
+
+Tenant Admin Support
+- Filament action “Download all photos” (Event resource) queues a server-side ZIP export via `GET /tenant/events/{event}/photos/archive` for authenticated tenants.
+- Only approved photos are included; failed assets are skipped with logging.
+
+Future Enhancements
+- Background job + notification for large ZIP exports (current implementation streams synchronously).
+- Optional passcode/PIN layered on top of join tokens for sensitive events.
+- Aggregate analytics (views/downloads per photo) presented in Tenant Admin dashboards.
