   RE-SKIN CONTRACT (per-vertical templates: hotels, supermarkets, ...):
   a vertical build overrides ONLY these surfaces, nothing structural:
     1. The tokens below (accent hue, cinema depth) if the vertical brand needs it.
     2. assets/img/hero-building.png  — one aerial plate of the vertical's building.
     3. Copy slots marked data-vertical in the HTML (building nouns, equipment
        examples, proof rows filtered to the vertical).
   Everything else — layout, motion, disclosure wiring, CTA pair — is the master
   template and should not fork. */
