/* ============ INNOVATIVE SURFACE — Verifica di Capitolato ============

   Landing B2B per studi di architettura. Un solo sistema per tutta la pagina:
   - i colori vivono nei token; la banda scura (.zone-alt) li ridefinisce
     invece di duplicare i componenti;
   - palette e caratteri sono quelli del manuale di brand identity IS:
     #141414, #FFFFFF, #C7C3BC, #C5B79C e Helvetica Neue. Gli unici toni in
     piu' sono tinte di questi quattro (linee, testi secondari) e il rosso
     funzionale degli errori del modulo;
   - raggio zero ovunque, nessuna ombra decorativa, nessun gradiente se non
     le velature sulle fotografie: il colore in pagina e' quello della materia;
   - il movimento ha un solo vocabolario (opacity + transform, --ease),
     dichiarato in fondo al file.
