 * Direction : retro-futuristic HUD militaire.
 *
 * Pédagogie :
 *   - Bootstrap 5 sert pour le grid + utilitaires, mais on OVERRIDE tout
 *     visuellement avec un namespace `an-*`. Bootstrap reste un grid system.
 *   - Toutes les couleurs et tokens sont en variables CSS : centralisés.
 *   - On fait du glassmorphism via backdrop-filter — rendu GPU, performant.
