/* ==========================================================================
   LE SURPLOMB - salle de bloc, Nantes Chantenay
   --------------------------------------------------------------------------
   Aesthetique : "sportif-mineral". Ce n'est PAS un design system officiel,
   c'est du CSS natif (Grid + custom properties). Aucune dependance npm.

   Verrous de coherence appliques dans toute la page :
   - Un seul accent : --accent (orange brique). Aucune autre couleur d'accent.
   - Un seul rayon : 0px partout, boutons compris (systeme "tout angle vif").
   - Un seul theme a la fois : clair OU sombre, jamais une section inversee.
