/**
 * content.css: /blog, /blog/<slug> and /changelog (ACT-249).
 *
 * A port of the design system's `ui_kits/website/Actorly Blog.dc.html`, `Actorly Article.dc.html` and
 * `Actorly Changelog.dc.html` (skill actorly-design): the inline styles of the specimens, as classes on the tokens.
 * Every colour is a token from design-tokens.css; sizes the tokens do not name are in rem (1rem = 16px).
 * The card tints are the specimens' own oklch values. Motion is public/js/content-pages.js (pills, copy link) and
 * motion-kit.js (the reveals).
