   Come funziona il tema:
   - :root         → dark, il default
   - @media (prefers-color-scheme: light) :root:not([data-theme="dark"])
                   → light se il sistema lo chiede E l'utente non ha
                     scelto esplicitamente dark (funziona anche senza JS)
   - [data-theme="light"] → scelta esplicita dell'utente, vince sempre
   I due blocchi light devono restare identici: se tocchi uno, tocca l'altro.
