/* ===========================================================================
   Mentat docs stylesheet.

   Port of the blog design (src/styles/global.css in the blog repo, an Astro
   site) onto the Jekyll-rendered docs, via the Morpheus docs port. Sections
   "design tokens" through "theme switch" are carried over verbatim; the final
   section adapts the design to the HTML that GitHub Pages' GFM pipeline emits
   for Markdown.

   Three theme states, and the order matters:
     1. bare :root            -> the complete light palette
     2. prefers-color-scheme  -> dark, but only when not explicitly set to light
     3. [data-theme="dark"]   -> explicit choice wins over the media query
   Every token is defined in state 1, so nothing depends on a media block
   being matched.
