/*
 * jwcarman docs theme — shared across the jwcarman OSS documentation sites.
 *
 * Tokens: Ink (header, dark ground), Cobalt (links, actions), Signal (amber —
 * rationed to focus rings, dark-mode link hover, and whatever per-project
 * signature element a site chooses), Paper and Slate (light and dark page
 * grounds).
 *
 * This file is the shared theme and carries nothing project-specific. To
 * adopt it: copy it, paste the theme block into mkdocs.yml, and give the
 * landing page a .jw-hero (title, .jw-hero__tagline, .jw-hero__actions).
 * A site's signature element, if it has one, lives in its own stylesheet
 * next to this one (codec's hex tape is in codec.css).
