   VAAD — charte « vert forêt » (voir CHARTERTE.md, déduite de apps/style.css).
   - Lime #76b900 réservé à l'accentuation : CTA, liens, focus, succès,
     indicateurs. Jamais de texte courant en lime, jamais blanc sur lime.
   - Hiérarchie par la taille et la graisse (600/600-700), pas par la couleur.
   - Échelle de verts #0f1f18 → #152820 → #1f3a2e → #2d5a3e ; bleu nuit
     #1a1a2e réservé au fond de page.
   - Breakpoint unique : 768px.
