/* Explore TrustyDr — public product tour.
   ---------------------------------------------------------------------------
   A provider should be able to see what they are signing up for before they
   create an account. This page is a guided walk through real screens, grouped
   by platform, with a CTA at the end of each track.

   Generated by scripts/build_explore.py from content/tour.json — the layout
   here never needs to change when a screenshot is added or replaced.

   Uses the site tokens in styles.css. No build step, no framework. */
