/* builds.one — one chat, every agent. Dark-first; every colour has one meaning.
   violet = frontier · cyan = routing/evidence · lime = local/Chameleon · amber = the one · coral = budget alerts.
   Motion: transform + opacity only. No filter, no backdrop-filter — the phone pays in frames, not bytes.
   Anything a script moves or redraws every frame sits on its own layer (will-change), so WebKit repaints that
   element and not the shadowed card, header or stage around it. */
