/* =========================================================================
   La Musica Live — Redesign Design System
   =========================================================================
   Foundation CSS per il redesign dark editorial (Iterazione grafica 2026-07).
   Carica DOPO Tailwind CDN + tailwind.config, in modo che le utility Tailwind
   possano leggere queste CSS variables tramite theme.extend.colors.

   Struttura del file:
     §1  @font-face self-host (Inter, Montserrat, Material Symbols)
     §2  CSS variables — palette dark (default)
     §3  CSS variables — palette light (override)
     §4  Base body + typography
     §5  Componenti custom non esprimibili in Tailwind utility
         (glass-panel, stage-glow, card-glow, hero-gradient, scrim-bottom,
          brand-gradient-text, map-marker)
     §6  Utilities light-mode override (glow attenuati su bg chiaro)
     §7  Material Symbols base

   Vedi docs/ridisegno_grafica.md §4 per il mapping dark→light.
