Five stacked optimisations for the thumbnail hot path so the timeline grid lands in fewer round trips and fewer bytes. 1. PhotoThumbnail: switch from 'medium' (640px) to 'small' (240px) for grid cells. 240px oversamples 150-200px logical cells on 2x retina and drops payload 5-8x. Lightbox and preview filmstrip keep 'large' and 'medium' respectively. 2. nextcloud_dav: pool the httpx client. A module-level AsyncClient with HTTP/2 + keepalive (max_connections=64, keepalive_expiry=120s) replaces the per-request constructor that paid a fresh TCP+TLS handshake on every preview fetch. Auth is per-user so it stays at the call site via auth=BasicAuth(...). Lifespan-managed: init in main.py's lifespan startup, aclose on shutdown. requirements.txt gains the http2 extra to pull in h2 (not currently installed). Same change applies to fetch_memories_info_async since it hits the same host. 3. PhotoThumbnail img: add decoding="async" so JPEG/WebP decode moves off the main thread, plus fetchPriority="low" so grid backfill doesn't fight UI fetches. 4. Eager-load Photo.user via joinedload from the thumb handler. _get_photo_with_share_fallback gains an options parameter so other callers stay zero-overhead; only the thumb handler asks for the owner join. Eliminates the second SELECT users per request. 5. Disk-fallback path picks up Cache-Control: private, max-age=86400 in both the FileResponse and X-Accel branches so re-renders match the NC primary path's caching behaviour. Net: a warm grid page should drop from ~200-400 ms median per thumb to well under 100 ms; payload drops ~5-8x; backend sustains higher concurrency with fewer sockets to Nextcloud and one fewer Postgres round-trip per request.
