/* CloudScout — agentic visual system v2 (2026-05-28).
 *
 * Dark, near-black surface. Semantic accent palette:
 *   sage  → verified $       (alive)
 *   gold  → advisory in flight (pending)
 *   rose  → dispute / blocked (broken)
 *   lilac → AI / agent reasoning
 *
 * Mono for IDs, hashes, agent-stream lines. Display for headlines.
 * The demo workspace (cs-demo-*) opts back into a daylight palette
 * so the dashboard surface still feels like a dashboard.
