/* ============================================================
   v4.6 — Isolation contre les fuites CSS du thème hôte.
   Les templates blog/article/prose des thèmes WP appliquent souvent
   des styles globaux (article p, .entry-content *, etc.) qui héritent
   dans notre widget quand il est injecté dans le DOM de la page.

   Stratégie SÛRE :
   1. Sur les containers racines : all:revert + re-déclaration de nos vars
   2. Sur TOUS les descendants : reset des seules propriétés "safe à forcer"
      (letter-spacing, text-transform, text-shadow, word-spacing, text-decoration)
      — celles qu'on n'utilise volontairement PAS dans le widget, donc aucun
      risque de casser nos propres styles.
   3. Sur les enfants critiques (h3, p, button, form) : override explicite
      des propriétés que le thème est susceptible de leaker (color, background).
   4. font-family / font-size / color sont préservés par héritage naturel depuis
      les containers, on ne les force PAS avec !important (sinon on casserait
      var(--dm-font-head) sur .dm-chatbot-header h3).
