/* ==========================================================================
   Base layout - shared by every theme.

   This file owns structure only: grids, spacing, states, responsive
   behaviour. Every colour, font and border radius comes from a custom
   property that the active theme's stylesheet defines, once for light mode
   and again under [data-theme="dark"].

   The contract a theme must fill:
     --bg --surface --surface-2 --ink --ink-soft --accent --accent-deep
     --line --line-soft --font-display --font-body --radius
     --k1..--k6 (cover swatch backgrounds) and --k1-ink..--k6-ink

   Optional, with sensible defaults below:
     --section-y (vertical rhythm)  --gutter (horizontal padding)
     --measure (container width)
