   ProPulse — site public

   Couleurs : charte de l'app (src/theme/propulse.ts) — navy, bleu, orange.
   Typographie : système ESOLVE repris de Bid Studio — Manrope pour les titres,
   Hanken Grotesk pour le texte. Les deux polices sont VARIABLES et
   auto-hébergées (58 Ko au total, aucun appel à Google).

   Animation : chaque <section data-act> est plus haute que l'écran et contient
   une .stage collante. app.js y écrit --p (0 → 1), la progression du scroll
   DANS l'acte, et le CSS ne fait que la lire. Les éléments [data-from]/[data-to]
   reçoivent .is-on dans leur fenêtre, et --fp leur progression locale.
