   health-dashboard.css
   Location: frontend/styles/health-dashboard.css

   Companion stylesheet for frontend/pages/health-dashboard.js (the Service
   Status surface). Every rule maps to an hd-* / hd__* class emitted by that
   module. Brand tokens inlined per the convention in regulatory-flags-admin.css
   (no CSS vars). Palette matches the app: brand green #015441, IBM Plex Sans,
   #F4F6F8 canvas, white cards with #E5E7EB borders.

   Status colours follow Lesson 41 — RED is reserved for genuine absence of
   relied-upon data ("No data"); overdue is amber, current is green, idle is
   neutral grey. No loud colour-key legend (aesthetic-restraint).
