   Versione HTML/CSS del componente GlowCard. Il JS (main.js) aggiorna

   Colore: --glow-base è la tinta di partenza (0 = rosso, 30 = arancione),
   --glow-spread quanto cambia muovendo il mouse da sinistra a destra.
   Il design system chiede un glow minimo: intensità ridotta rispetto alla versione precedente. */
