/* MeMori — la Pila nello stile «Ritagli» (28/10/2026, prova in tools/prova-pila): titolo col numero,
 * i giorni d'attesa, la scala e il giudizio della Home; la pila di dorsi dritti (scelta dell'utente:
 * niente libri storti), ritagli di colore pieno con larghezza, spessore e spostamento diversi, sul
 * piano senape con l'ombra d'inchiostro, il primo comprato contornato di senape; «Pesca a caso».
 * Accanto «Leggilo per primo!» e le cifre (pagine, altezza, il più vecchio); sotto l'elenco in ordine
 * d'acquisto coi giorni in un bollino che si scalda col tempo (--heat). Vale solo dentro #pile-view.
 * Caratteri e colori: ritagli.css. Animazioni: motion.css (D10) e motion.js («Pila»). */
