   Base V1: avorio, inchiostro, filetti sottili, Inter, cerchi numerati.
   Regia V2: una scena notte che si apre da un cerchio, parole che si accendono.
   Un solo sistema: due toni che si invertono, angoli vivi e cerchi, un solo accento blu che segna ciò che è attivo.
   Tutte le distanze usano una scala sola: 8 · 16 · 24 · 32 · 64 · 104.

   blocco in lettura si accende.
   Le classi le mette uno script (scroll.js): is-lit sulla sezione (lo script è partito) e is-on sul blocco e sul
   titolo dell'indice in lettura. Senza script i titoli sono tutti in inchiostro e senza punto. Il passaggio di
