   Palette is a graphite/ink control-room base with two accents
   that are not decoration — they are the product's own signal
   colors: teal is what the agent calls "tier-1" (safe, resolved
   automatically), amber is "tier-2" (paused for a human). Both
   colors recur everywhere in this site with that exact meaning,
   including the live demo output.
