/* ============================================================
   Brand Detail Panel — full-bleed bento overlay.
   Phase 1: Альфа-Банк pilot.

   Architecture:
   - .brand-detail-overlay  — fixed 100vw×100vh root, z-index 10100
                              (above brand-picker portal at 10080).
                              Receives scoped --brand-* vars per active brand.
   - Brand-zone (DNA)       — anything inside .brand-detail-bento uses
                              brand colors / fonts / shadows. Hairlines
                              via color-mix with --brand-text.
   - Kvill-zone (DS-4)      — overlay chrome (close X, focus rings,
                              prefers-reduced-motion fallback motion)
                              uses DS-4 tokens (var(--fg-*), --bg-*,
                              --ease-*, --shadow-*).
   - Brand fonts            — only inside [data-brand-fonts] surfaces,
                              never leaks to overlay chrome.

   Motion choreography (800ms total):
     0–80ms     anchor lock (pure no-op — ensures consistent FLIP origin)
     80–280ms   clip-path circle expansion from click point
     280–520ms  hero typographic claim (initials + wordmark)
     520–760ms  bento materialization (staggered cells from center)
     760–800ms  settle — cursor halo fades in

   Skip-mode (240ms): single fade-in, no choreography. Triggered by
   localStorage view-counter (>=3) or prefers-reduced-motion.
