   is each project's brand accent, injected per-card as --proj and used ONLY for
   graphic channels — key bars, dots, sparkline strokes — never body text); and
   glass material lives ONLY on the nav rail, the top bar and overlays. All
   content surfaces are opaque (.card / --surface / --raised).
