   Ruach Hub — assets/css/theme.css
   Styles structurels du thème : reset léger, typographie de
   base, header/footer PHP natifs, boutons, cartes, hero, et
   composants UI repris fidèlement du design system Ruach Hub.
   ------------------------------------------------------------
   Charger APRÈS tokens.css. Ces styles habillent le HTML PHP
   (header.php, footer.php, templates) — ils n'interfèrent pas
   avec le contenu construit dans Elementor (voir
   elementor-overrides.css pour les ajustements côté éditeur).
