/*
  SeisMeteo — stile del sito seismeteo.com (design "v3", ottobre 2026)

  Home: testata e hero "giorno sopra, notte sotto" con la traccia sismica come
  orizzonte, poi sezioni scure (ritorno, iPhone Duo, funzioni, Gratis/Pro).
  Pagine interne: testata compatta scura e colonna di lettura su fondo scuro.

  Linee guida di marketing di Apple: il sito non disegna prodotti Apple. I
  dispositivi sono le cornici ufficiali di Apple Design Resources (iPhone 18
  Pro Max e iPhone Duo), unite alle schermate vere dell'app in un'unica
  immagine da strumenti_cornici.py e mostrate così come sono: niente
  inclinazioni, ritagli, ombre aggiunte o animazioni. Si animano solo testi e
  grafiche del sito.

  Animazioni (solo con prefers-reduced-motion: no-preference):
  - scroll-driven in CSS, dentro @supports (animation-timeline: view());
  - se il browser non le supporta (o con ?fallback=1) site.js mette la classe
    "no-sda" su <html> e pilota le stesse animazioni con IntersectionObserver
    e variabili CSS (--t) aggiornate a ogni frame di scorrimento.
  Senza animazioni la pagina è statica e leggibile: testi e riquadri visibili.

  Nessun attributo style nell'HTML (la CSP ha style-src 'self'): le variabili
  impostate da site.js passano dal CSSOM, che la CSP non blocca.
