/* =========================================================
   Domea · foglio di stile

   La pagina è statica di base. Le scene legate allo scorrimento
   si attivano con due classi su <html>, messe da boot.js:
     .pin  JavaScript attivo e schermo abbastanza alto: scene
           "Una giornata" ed "Energia" bloccate durante lo scroll
     .fx   come .pin, ma senza "riduci movimento": anche hero,
           manifesto, binario delle soluzioni e privacy
   Senza classi (niente JS, schermo basso, meno movimento) ogni
   sezione è un blocco normale, leggibile e senza tagli.

   Animazioni: ease-out forte per le entrate, uscite più rapide
   delle entrate, solo transform e opacity.
