   /beta — la page d'installation
   ------------------------------------------------------------
   Chargée APRÈS style.css, dont elle réutilise les tokens, les
   boutons et le fond. Elle ne redéclare rien : elle ajoute la
   carte d'installation.

   Contrainte de conception : tenir sur UN écran de téléphone —
   logo, indicateur d'étape, un bouton principal, « Ça bloque ? ».
   Tout le reste est replié.
