 * GMW — new design system (visual overhaul).
 *
 * Replaces the old teal-cyan + purple + glassmorphism language with a warm,
 * signal-driven ops-console aesthetic. Hierarchy comes from scale/weight and
 * tonal surface blocks, NOT from borders/shadows. Three semantic signals:
 *   lime  = OK / live      (--signal)
 *   amber = warn           (--amber)
 *   vermilion = flag/danger (--vermilion)
