   Menti Unite — redesign v8 (da «Menti Unite - Redesign.dc.html», Claude Design)

   Si carica DOPO base.css e menti-unite.css: ridefinisce i token (colori,
   caratteri, raggi, ombre) e ridisegna le parti principali.
   - Caratteri: Geist e Geist Mono, in locale (la CSP ammette solo 'self').
   - Colori: inchiostro #0b0c10, fondo #f5f6f8, cremisi #c2183f.
   - Home nuova (hero con codice a caselle, scheda Live, formati, «Conduci»).
   - Telefono: opzioni con chiave e pallino, card bianche ad anello.
   - Schermo: palco scuro con barre cremisi, fascia «partecipa» con codice
     a caselle, comandi con i tasti.
   I temi di sessione (mu-theme.js) continuano a cambiare --color-primary*.
