   REFINE — the final UI layer.
   Loaded last, so it has the final say.

   Three problems this fixes:
   1. NO HIERARCHY. Every section was ~700-1000px and shouted at the
      same volume, so nothing landed. Now the page has cadence:
      sections breathe differently, and the important ones dominate.
   2. NO TYPE SCALE. Sizes were ad-hoc. Now there is a real ratio,
      with fluid clamp() so it holds from 360px to 1600px.
   3. CONTACT WAS BURIED. A sticky action bar keeps Call / WhatsApp /
      Book one tap away, always.
