Replace dufs's plain file list with a React 19 + Vite + TypeScript SPA served same-origin by dufs, so the cloud URL becomes a real gallery behind the existing auth: thumbnail grid, image lightbox (zoom + keyboard nav), inline video, drag/ pick upload, download, confirm-guarded delete, and a simple .txt/.md editor. Serving architecture (de-risked against the real dufs 0.46.0): --assets does not override the UI, so dufs `render-spa` serves the app shell, the SPA lists dirs via WebDAV PROPFIND (render-flag-immune) and streams files via GET (Range for video seeking), with HashRouter so navigation stays at "/". Verified render-spa leaves KeePass file GET/PUT/?hash intact (Phase 1 unaffected). Adds generate_thumbnails.sh (ImageMagick images + ffmpeg video posters → ~/cloud/.thumbs, idempotent) and setup_cloud_gallery.sh (build + deploy the SPA into the cloud root, enable render-spa, wire thumbnail refresh into the Phase-2 media sync). setup_dufs_cloud.sh now emits render-spa only when the SPA is deployed, so a fresh dufs keeps its default listing. Verified: pnpm build + lint (strictTypeChecked) clean; 38 vitest tests, coverage 92.8% stmts / 96% lines (dufs-client 100%); local dufs --render-spa serves shell + assets + thumbnails + PROPFIND (all 200). Live deploy left for the user (needs sudo; enables render-spa on the public service). Note: host ffmpeg is broken (libvpx.so.11) so video posters are skipped until it's fixed.
