/**
 * Lotus d'Or Newsletter & Ebooks — styles publics par défaut (Étape 9).
 *
 * Portée : uniquement les éléments préfixés ".lon-" générés par les
 * shortcodes publics des Étapes 6/7 (formulaire d'inscription,
 * désinscription, demande RGPD, blocs ebooks).
 *
 * Conçu pour être surchargé facilement par le thème actif :
 *   - toutes les couleurs/espacements passent par des variables CSS
 *     "--lon-*" déclarées sur :root, à redéfinir dans le thème pour
 *     adapter l'habillage sans toucher à ce fichier ;
 *   - sélecteurs à une seule classe (faible spécificité) ;
 *   - aucun !important, sauf le strict minimum documenté ci-dessous ;
 *   - la police héritée du thème (font-family: inherit) plutôt
 *     qu'imposée par le plugin.
