   LANDING-DECK — base.css
   STRUCTURE COMMUNE. AUCUNE COULEUR NI POLICE EN DUR.
   Tout passe par des variables CSS redéfinies dans themes/<nom>.css.
   Contrat de variables attendu (voir README.md) :
     Couleurs : --bg --bg-alt --ink --muted --accent --accent-2 --accent-ink
                --card-bg --card-border --nav-bg --footer-bg --footer-ink
     Typo     : --font-display --font-body --weight-display
     Forme    : --radius --radius-lg --shadow --shadow-lg --border
     Divers   : --maxw --section-pad --nav-blur
   base.css ne fait QUE consommer ces variables (jamais de #hex ici).
