- Added public gallery API with token-expiry enforcement, branding payload, cursor pagination, and per-photo download stream (app/Http/Controllers/Api/EventPublicController.php:1, routes/api.php:16). 410 is returned when the package gallery duration has lapsed.

- Served the guest PWA at /g/{token} and introduced a mobile-friendly gallery page with lazy-loaded thumbnails, themed colors, lightbox, and download links plus new gallery data client (resources/js/guest/pages/PublicGalleryPage.tsx:1, resources/js/guest/services/galleryApi.ts:1, resources/js/guest/router.tsx:1). Added i18n strings for the public gallery experience (resources/js/guest/i18n/messages.ts:1).
- Ensured checkout step changes snap back to the progress bar on mobile via smooth scroll anchoring (resources/ js/pages/marketing/checkout/CheckoutWizard.tsx:1).
- Enabled tenant admins to export all approved event photos through a new download action that streams a ZIP archive, with translations and routing in place (app/Http/Controllers/Tenant/EventPhotoArchiveController.php:1, app/Filament/Resources/EventResource.php:1, routes/web.php:1, resources/lang/de/admin.php:1, resources/lang/en/admin.php:1).
