The service worker uses staleWhileRevalidate on /dist/*, so after a
release it would serve old bundles from cache indefinitely (cache is
only wiped when the cache *name* changes, which was hardcoded to
'dashcaddy-shell-v10'). Result: dashboard appears unchanged after a
self-update until the user manually unregisters the SW.
build.js now hashes the concatenated dist bundles and writes
`dashcaddy-shell-<10-hex-chars>` into sw.js. Any change in dist/
produces a fresh cache name; on the next page load the SW's activate
handler deletes all older caches and the new bundles are fetched.
Server-side batched /api/v1/services/status endpoint replaces N
individual browser probes with a single API call (HEAD-first with
GET fallback, concurrency-limited, CA-aware HTTPS agent).
Frontend: clock reuses DOM instead of rebuilding innerHTML every
second with drift-correcting timer that pauses on hidden tabs.
Card animations use CSS transitionDelay + requestAnimationFrame.
Internet dot blink moved from JS intervals to CSS keyframes with
prefers-reduced-motion support. Service worker rewritten with
network-first navigation, stale-while-revalidate assets, and
navigation preload. Font faces drop TTF fallbacks, use font-display
swap.
