/* etminan handbook — theme override for Material for MkDocs.

 * Recolors Material's `slate` scheme to the hand-built etminan.dev palette and
 * pins the font stacks. No @font-face, no CDN — matches the site's privacy
 * posture. `font: false` in mkdocs.yml only *removes* Google Fonts; the
 * --md-*-font-family overrides below are what actually install our stacks.
