/* ==========================================================================
   Theme
   --------------------------------------------------------------------------
   This file is the single source of truth for the visual theme: design
   tokens (colors, typography, spacing, layout, radii) and the syntax
   highlighting palette. To re-theme the docs, swap THIS file only — the
   structural CSS in style.css references everything through these tokens
   and the `.tok-*` classes defined below.
