/* ============================================================
   GUIDED SURGERY — the section under the six blocks
   The only place on the home page where the service itself is
   explained. Three parts: an opener that states the promise, five
   clinical steps, and the case TYPES a dentist can find himself in.

   Everything reuses the tokens already in this file — navy, the
   steel greys, 18px radii, hairline borders, the same lift on
   hover. No new colour and no new shape enter the site here.
