/* Marturia docs — shared design system.
   Mirrors the landing-page tokens (forest green + warm cream on near-black)
   so docs feel like the same product, not a different site.

   Layout: persistent left sidebar + scrollable content. Sidebar collapses
   to a hamburger under 900px so phone-reading the quickstart still works
   (a lot of "I'm at a customer's site verifying a receipt" flows happen
   on mobile). */
