Server-side icon cache (lib/health/icons.js + GET /api/icons/:slug.png) fetches
each icon once from dashboard-icons into a persistent dir and serves it from the
LAN. Browser never contacts the CDN; slug sanitized; first-letter fallback.

Two-band dashboard: draggable data cards (clock/weather/host-perf/speedtest/
jobs/inbox/search) + Little Blue read-only Health band (config registry +
pg-boss health engine + grouped service tiles w/ auto-icons). Refined-B chrome,
server-side layout persistence, polling refresh. Fix-it agent deferred.
