/**
 * Permathèque — Rendu front-end des blocs Editor.js (BlockRenderer PHP)
 *
 * Toutes les classes sont préfixées `ph-` pour ne jamais interférer avec
 * l'existant. Ces styles s'appliquent au HTML généré par BlockRenderer
 * quand une page/post a un `content_blocks` non-null.
 *
 * Philosophie :
 *  - Utilise les tokens CSS existants (--primary, --color-text, --color-border…)
 *  - Dark mode via variables (aucun selector .dark-mode ajouté ici)
 *  - Responsive par défaut, fallback gracieux sans JS
