/* ==========================================================================
   NetBridge Marketing Suite — page.css (styles propres à la page d'atterrissage)
   --------------------------------------------------------------------------
   Chargé APRÈS css/tokens.css, css/fonts.css et css/components.css (copies du
   système UI NetBridge, /workspace/netbridge-ds/). Les quatre feuilles sont liées
   en parallèle dans index.html plutôt qu'avec @import (pas de cascade bloquante).
   Tous les blocs de contenu utilisent les composants .nb-* du système ; ce
   fichier ne fait que la mise en page de la page (préfixe .lp-).

   Règle : couleurs, polices, tailles de texte, espacements, rayons, ombres,
   durées et z-index viennent UNIQUEMENT des jetons --nb-*. Seules valeurs
   brutes : points de rupture (640 / 768 / 1024 px, ceux du système, et 680 px, bascule mesurée du logo ; les media
   queries ne lisent pas les variables), largeur du texte du héros et du
   visuel (valeurs du README du visuel de Ti-Pixel), pentes vw des clamp()
   (bornes = jetons).
