/* ============================================================
   PENSÉE IA — src/styles/theme.css · Identité KWENI LABS
   Pensée est un produit KWENI LABS (charte graphique KWENI v1.0) :
   - le point Labs : un carré divisé en grille 2×2 Signal. Il reste
     vivant : en réflexion, des ondes carrées s'en propagent ; en
     écriture, il bat doucement
   - le carré comme ponctuation : conversation active, titres, curseur
   - le fil de pensée : ligne qui relie le point à la réponse
   - Montserrat partout, JetBrains Mono pour le code
   Chargée après les autres feuilles : elle a le dernier mot.
