/* Design tokens and shared components for every extension page, and for the
   overlay's shadow roots on youtube.com (hence :host next to :root).
   Values are measured from languagereactor.com (computed styles, Chrome
   DevTools protocol, 2026-09-23). The reference is dark-only. Its purple is
   Wovia's blue and yellow (owner, 2026-10-12), from brand.css.

   The panel page, in the extension and on the website, has a light and a
   dark look (owner, 2026-10-14: Safari's grounds on iOS, light by default),
   chosen by the setting `theme` and written on its root as data-theme
   (panel/theme-mode.js); the blocks below the first redefine the tokens for
   each. Everything else keeps the first block's, the reference's dark: the
   overlay and the subtitle frame, whose :host resets the tokens inside its
   shadow root, and the extension's other pages. A stylesheet names a token
   for every colour of the page's own surfaces; white over a picture, a video
   or a coloured fill is --on-media or --on-accent, the same in both looks. */
