   MERIDIAN — design system + components
   --------------------------------------------------------------------------
   Type: one grotesque (Inter) for everything, one mono (IBM Plex Mono) for
   technical metadata only. No serif. Premium apparel sites studied in
   _research/brand-teardown.md §E are overwhelmingly grotesque-only; the mono
   is the one deliberate voice, and it carries the "archive plate" idea.

   Colour: neutral by rule (§F). Exactly one accent, used only for state
   (low stock, error). Colour comes from the garments, never from the UI.
