/* ENSEMBLE! — client site, design « la nuit et le dégradé » validated on 15-10-2026 (mix of designs A and B):
   starry night at the top with the big official logo (straight), the orange → violet gradient of the former site for
   « Comment ça marche », white cards on the night, oblique edges between the parts, a sticky menu that shows the small
   logo once the big one is gone. Montserrat (self-hosted, OFL) for titles, the system stack for text. CSP: 'self' only. */
