   PLAN2SECURITE — feuille de style

   Charte tirée du logo : treize tuiles de couleur, lettres blanches.
   Le site reste blanc et sobre — c'est un métier de précision — et les
   couleurs du logo n'y reviennent qu'en touches : filets, pastilles,
   bandeaux des types de plans. Le vert et le rouge des plans eux-mêmes
   (évacuation, intervention) sont ceux que fixe la norme.

   Pas de police chargée depuis un tiers : pile du système.
