/* ============================================================================
   pf-landing-2026.css — Élévation PREMIUM (additive) de la vitrine publique
   pulsiforms_landing_vision.html (servie à "/").
   ----------------------------------------------------------------------------
   OBJECTIF : niveau SaaS 2026 (Stripe/Linear/Vercel) + conversion visiteur →
   connexion, EN CONSERVANT le contenu éditorial et toutes les affirmations
   verrouillées (tests tests/regression/landing-wysiwyg-stability-claims.test.js).

   CONTRAT :
     • Purement ADDITIF. Chargé APRÈS le <style> inline → gagne la cascade à
       spécificité égale, sans !important.
     • Réutilise les tokens de marque déjà définis dans le <style> inline
       (--gold, --gold-l, --gold-p, --g1..g3, --gray, --gray-l, --white,
       --gold-faint) : AUCUNE nouvelle couleur de marque, AUCUNE var globale
       redéfinie.
     • Aucun script requis : les CTA restent câblés par modules/landing-vision.js
       via [data-pf-nav] (CSP script-src 'self' respectée).
