/* AGRANDISSEMENT DU TEXTE · revu le 2026-08-27.
 *
 * Deux facteurs se MULTIPLIENT desormais, au lieu de s'ecraser :
 *
 *   --a11y-zoom : le reglage A / A+ / A++ de ce panneau ;
 *   --pref-zoom : la taille de police que le visiteur a choisie dans son
 *                 navigateur, posee par a11y.js (1 = 16 px, 1.25 = 20 px).
 *
 * Pourquoi passer par « zoom » plutot que par les rem : l'immense majorite
 * des tailles du site sont ecrites en pixels (frameworks tiers compris).
 * Les convertir une a une serait long et risque ; le facteur, lui, agrandit
 * TOUT, sur toutes les pages, y compris pe/, admin/ et les studios. */
