/* ============================================================
   Alba · Landing di download (getalba.app)
   ============================================================
   Token allineati al design system dell'app (apps/web/src/index.css).
   Differenze volute rispetto all'handoff di design:
   - --ink-3 / --ink-4 usano la scala accessibile dell'app
     (#736d65 / #948d84) invece di #8b847d / #b5ada4: i valori
     originali non passano 4.5:1 sul fondo crema.
   - dimensioni tipografiche in rem, così il testo scala con la
     preferenza font-size del browser/OS.
   - aspect-ratio del telefono 620/1251: gli screenshot sono
     ritagliati sotto la status bar iOS e sopra gli angoli scuri
     del device (vedi scripts/gen-site-assets.mjs), cosi non si
     sommano due telai.
