/* ============================================================================
   ouRGeo — shared design system
   ----------------------------------------------------------------------------
   Shell components — the frame, header/nav, mobile drawer, footer, buttons,
   forms, avatars, geo-sections — shared by every page on the site.

   Colour lives in assets/css/tokens.css, which every page links BEFORE this
   file. There is no token block here any more: there used to be one, copied
   into the inline <style> of each marketing page, and keeping five of them in
   step was a standing invitation to drift. Add a colour there, not here.
