/* ============================================================
   alarme-saint-malo.fr — feuille de style unique
   Charte dérivée du logo : navy #12263F, rouge #AF2122,
   teal #2A7D93, gris pierre #7E858F. Aucune dépendance.

   Répartition des rôles, à ne pas mélanger :
     rouge = appel à l'action et accent fort (rare, donc visible)
     teal  = filets, puces, numéros, liens (fréquent, donc doux)
     navy  = texte, titres, fonds sombres
