- sw.js + manifest.json: cache-first service worker for instant repeat-visit loads and full offline use. Registered only when window.CHESS_PWA is true. - Disabled by default: an active SW serves returning visitors from cache, so they'd stop hitting the server and disappear from the Fly logs. Enable at build time with --build-arg ENABLE_CHESS_PWA=1 (Dockerfile flips the flag); ENABLE_CHESS_PWA=1 make dev does the same locally. - scripts/bump_version.sh + 'make bump': bump the asset cache version across index.html (?v=N) and sw.js (CACHE) in sync. Required before deploy so the service worker / browser cache pick up changed assets. Bumped v25 -> v26. - README: document cache versioning + PWA flag.
