   site.css - LE GABARIT COMMUN DU SITE v3 (maquette, 2026-09-15).
   Tout est en jetons : une valeur change ici, elle change partout.
   Deux registres : les pages SOBRES (papier, encre) et les pages de NUIT
   (`html[data-theme="nuit"]` : le selecteur et la home fidelite).
   Regles (PLAN-SITE-v3 § 9) : alignement a gauche, trois amplitudes d espace,
   un seul objet fort par page, aucun sur-titre en capitales, pas de trois
   cartes identiques, contraste 4,5:1, cibles de 44 px, lisible sans JS.
