/* ============================================================================
   Vetrina di Master Chess (index.html) — ottobre 2026.

   Foglio a sé: masterchess-theme.css resta a privacy.html, che non cambia.
   Tema unico scuro, come l'identità del marchio (navy + blu del logo): le
   catture dell'app sono scure e una pagina chiara le farebbe sembrare ritagli.
   Colori come token qui sotto; nessun colore scritto a mano nelle regole.

   Sei blocchi: hero, il percorso (telefono fisso che cambia schermata),
   oltre l'analisi, scarica o apri, chi sono con i contatti, piede.
