/* ==========================================================================
   /public_html/assets/css/mapa.css — MA Ayacucho (Producción)
   Propósito:
   - Vista de mapa limpia tipo inDrive (mobile-first).
   - Pantalla completa fiable (vh + svh/dvh), controles “glass” y leyenda.
   - Chips de estado (Disponible/Ocupado), FAB de centrar y sheet inferior.
   - Modo oscuro, safe-area (notch) y CSP estricta (sin inline).
