Backend (Go/Gin/pgx): env config, pgx pool with retries, Garage S3 client (path-style, region garage), embedded golang-migrate migrations, JWT auth with refresh rotation, albums CRUD, members/roles/invites with no-escalation matrix, photo upload + async imaging/goexif WebP variants, cursor pagination, presigned URLs, likes/comments, SSE hub (album + personal), notifications, share links. Frontend (SvelteKit 2 + Svelte 5 + Tailwind v4): API wrapper with 401 refresh, auth store, all screens, Uploader/PhotoGrid/Lightbox/Comments, SSE client with reconnect + REST catch-up, three themes + system via data-theme. Deploy without Docker: Makefile builds the frontend into backend/static and embeds it (go:embed) into a single statically linked binary; systemd unit and nginx SSE example included. Use gen2brain/webp (-tags nodynamic) instead of cgo kolesa-team/go-webp to keep CGO_ENABLED=0 static builds; design.md/proposal.md updated accordingly.
