 * Tokens live on :root (light) and are redefined for dark mode, both via
 * prefers-color-scheme and via an explicit [data-theme] override set by the
 * theme toggle (client/site.js). Embedded Askdown forms (@askdown/html's
 * askdown.css) are re-themed at the bottom of this file by overriding the
 * --askdown-* tokens, so previews and hosted forms share the site palette.
