/* CtrlFinder — un foglio di stile, organizzato per quello che si vede.
 *
 * Direzione: il design system di shapefinder.cc, ricavato con skillui e verificato sul CSS del sito.
 * Inter sola, palette calda e neutra (fondo #f5f5f4, fogli bianchi, testo #292524), niente accento
 * colorato: i pulsanti pieni sono neri, le piastrelle grigie, l'arancio resta al solo badge.
 * Raggio 8 px per i controlli, 15 px per i fogli, ombre a cinque strati, niente blur.
 *
 * Le comparse che partono da opacity 0 vivono sotto `.js` (index.html aggiunge la classe): senza
 * JavaScript il contenuto è leggibile e i crawler lo vedono.
