   OSFRIA — « Le réseau qui pense »  ·  Maquette Animiste-204
   Intégration CMS HETERACTIS — version mise en ligne.

   Deux registres :
     • body.is-home  → ACCUEIL nuit tech élégant (réseau de neurones,
       tokens streaming, terminal, waveform). Fond bleu nuit souverain.
     • body.is-page  → PAGES DE CONTENU sur fond CLAIR (lisibilité),
       même identité (header/footer/logo tricolore), effet fenêtre de
       code / terminal pour les blocs d'installation.

   Tricolore souverain OSFRIA :
     bleu encre #1B2A6B · ivoire chaud #F4EEDE · ROUGE FRANÇAIS #E1000F

   Perf : seuls transform / opacity / filter sont animés (GPU).
   Animations 100% CSS (scroll-driven natif), zéro JS d'animation.
   prefers-reduced-motion respecté.
