   Design system, redone after DroneSentry-C2 (DroneShield's real C-UAS
   platform — see CLAUDE.md): near-monochrome tactical, not pastel. The
   base is grayscale, desaturated real satellite imagery underneath; color
   is spent sparingly, on meaning only — one muted green for "ours/live/
   clear", one warm red for "threat/denied", amber for caution, everything
   else stays gray. No border-radius above 3px on chrome/rows: sharp reads
   as instrument. Color is never the only signal for a class — shape and
   text always corroborate it.
