/* MeMori — gli Scaffali nello stile «Ritagli» (28/10/2026, prova in tools/prova-scaffali): titolo grande
 * con il bollino del numero degli scaffali, raggruppamento a pillole con un'icona, «Colpo d'occhio»,
 * ogni scaffale un riquadro di carta con i dorsi dritti (forma F1 «Ritaglio»: colore pieno, angoli
 * di carta tagliata a mano, senza il segnalibro dello stato) su una mensola lunga colorata con
 * l'ombra d'inchiostro, i primi titoli e la barra di quanto è letto. Scaffale aperto: filtro per
 * stato, copertine come in Libreria (libreria.css), «Scaffali vicini». Vale solo dentro
 * #shelves-view (i dorsi .book-spine servono anche altrove). Caratteri e colori: ritagli.css.
 * Animazioni: motion.css (B2, i dorsi che scivolano; D7) e motion.js («Scaffali»). */
