   Static customer site. No build step, no framework. Mobile-first.
   Palette sampled from the client's own logo (dark teal + sage + a
   warm gold estimated by eye from the ring gradient — see FACTS.md).
   Animations are CSS-only (transitions + one keyframe fade), gated by
   prefers-reduced-motion — no JS animation library, per house rule.
