/* ==========================================================================
   Questelon design system
   One stylesheet for questelon.com and every product sub-site under it.

   Why this file exists: before 2026-08-19 every page carried its own <style>
   block. The three site copies in this repo had already drifted apart from one
   another, and the Questelon pages had accessibility work (mobile nav toggle,
   focus-visible, reduced-motion) that the Bountrek pages never received. A
   shared stylesheet makes that class of drift structurally impossible - fix a
   contrast ratio once and every page gets it.

   Structure:
     1. Tokens          - colour, type, space, radius, shadow (light + dark)
     2. Base            - reset, document defaults, focus, motion
     3. Layout          - page shell, sections, grids
     4. Components      - nav, buttons, cards, notices, footer
     5. Prose           - long-form legal pages
     6. Product themes  - per-product accent overrides
