Build and push server image / build-and-push (push) Failing after 1m10s
New third mode alongside photos/calendar: fetches a .whiteboard file over plain WebDAV (Basic auth -- generic, not Nextcloud-specific) and renders it via a small Node.js sidecar using Excalidraw's own real export code (@excalidraw/utils + @resvg/resvg-js, no headless browser), since a .whiteboard file turns out to be Excalidraw scene JSON, not an image. The sidecar runs as a second process inside this same container (Dockerfile installs Node, start.sh backgrounds it before exec'ing uvicorn) rather than a separate docker-compose service -- lightweight, stateless, reachable only at 127.0.0.1 from the Python process, nothing worth independently scaling. The rendered PNG is treated exactly like a photo from there on -- composed/quantized through the existing image_pipeline (letterboxed, never cropped) rather than a second parallel rendering pipeline. WebDAV credentials support the common "it's actually the same Nextcloud account as my CalDAV" case (an explicit opt-in checkbox, not silently inferred) while still working with any WebDAV server generically. Frame-level source (URL + owning account) follows the same owner- controls-their-own-data permission split as calendar sources and the week view's task list: only the account owner can point a frame at it, anyone linked can clear it. Honest limitation: this environment has no Node.js/npm, so render-service/ is written carefully against each library's documented API (verified via the npm registry, including transitive dependency licenses after the CalDAV/AGPL surprise earlier this session) but has never actually been executed. First real docker build is the first true test -- see render-service/README.md.
