/* ASR Quiz – teoria: blocchi di segnali nel testo e atlante dei segnali.
 *
 * Un solo foglio per il sito pubblico (.asr-site, dopo asr-site.css) e per l'area allievi / app
 * (.asr-scope, dopo asr-app.css). Usa i token comuni (--asr-color-*) con un valore di riserva:
 * le figure stanno sempre su bianco arrotondato, le schede seguono il tema (scuro o chiaro).
 *
 * Struttura:
 *   1. Blocchi .asr-signs nel testo  ({{asr_fig:REF}} → <img class="asr-sign__img">)
 *   2. Atlante: intestazione e gruppi
 *   3. Atlante: griglia e schede (sito: figura, nome, fatti, trabocchetti in <details>;
 *      app: schede-pulsante che aprono il dettaglio)
 *   4. Dettaglio di una figura nel modale (app)
