   TTIO — Calcolatore · MICRO-HOOK discreto · stile ISOLATO
   -------------------------------------------------------------------------
   Chiuso = callout leggero e compatto (non una banda protagonista, non una
   seconda hero): deve incuriosire senza mangiarsi la pagina. Click → espansione
   inline → RISULTATO "Opzione A": numero grande + testo forte, niente grafici,
   niente barra della vita, niente countdown. Il sonno è un confronto testuale
   secondario. Stesso componente per Home e Christmas. Nessun 100vh.
