/* Art-Design di Tiziana Sessa — «Materia e luce», CHIARA di base (03/10/2026, 21:00; Domenico: «metti la versione
   light come principale»). Lo scuro resta col pulsante luna/sole; tutti e due hanno i particolari del kit
   (decori, sigillo, pianta a tratto, logo intero a tratto, icone che si disegnano, fasce); testo grande, contrasto AA.
   Regole (Design/TEMA-E-LEGGIBILITA.md):
   - colori SOLO dai token semantici qui sotto. Il CHIARO sta in :root (e :root[data-theme="light"]), lo SCURO in
     :root[data-theme="dark"] e in ogni .scuro (l'anti-lampo scrive sempre data-theme="light" o "dark");
     .scuro rimette i valori scuri in un'isola (hero, panorama, piede: testo chiaro sopra foto o fondo noce);
   - testo corrente 17 px al telefono, 18 px da computer, interlinea 1,6;
   - sopra le foto il testo sta solo su un velo deciso; altrove le foto brillano;
   - da computer (≥ 1024 px) 1 u = 1 px di home-pagina.png: --u = min(100cqw, 1440px) / 750, colonna .col-u di 750 u;
   - ogni stato nascosto delle entrate vale solo sotto html.mo (JS attivo e movimento non ridotto). */
