   Amber Watch — design.css  (v2)
   "deep night sea with amber glow"

   Strategy:
   - Single dark navy base color shared by page bg AND every card.
   - Glass effect (rgba alpha + backdrop-filter) so cards emerge from the same
     atmosphere instead of stacking solid panels on it.
   - One accent ramp (amber) with a teal whisper used ONLY for fala/map water.
   - Glow is reserved for L3 + active gauge segments. Nothing else glows.
