/* =========================================================================
   V2.2.4 — CORRECTIONS DESIGN DE /chat/{id}
   =========================================================================
   La page chat/{id} était « complètement pétée » à cause de 4 bugs CSS
   cumulés :

   1. `.chat-wrap` est défini comme grid 2 colonnes (340px 1fr) pour la
      liste+room. Mais sur /chat/{id} il n'y a QUE la room → la grid
      casse tout (header écrasé à gauche, body à droite, composer en bas).

      → Correctif : ajout du modifieur `.chat-wrap--room` qui passe la grid
        en 1 colonne pleine largeur.

   2. `.chat-title` était utilisé dans le Blade mais n'existait pas en CSS
      (c'était `.chat-header-info`). Le titre n'était donc pas stylé.

      → Correctif : le Blade utilise maintenant `.chat-header-info`.

   3. `.chat-room-panel` (cadre arrondi + ombre) était défini mais jamais
      utilisé dans le HTML → la room flottait sans cadre.

      → Correctif : le Blade wrappe maintenant header+body+composer dans
        `.chat-room-panel`.

   4. `.composer-main` (wrapper input + send button) était défini mais

      → Correctif : le Blade wrappe maintenant input+send dans
        `.composer-main`.
