/* AGO Brandbook - its own small design system, deliberately not shared with ago-landing's
 * styles.css or ago-console's tokens.css: this page's whole job is to *display* those two files'
 * values as data (swatches, a type scale, the five icons), not to build a UI out of them. Sharing a
 * stylesheet would blur which colors are "the brand" and which are just this page's own chrome.
 *
 * No build step, no framework - the same shape ago-landing's own styles.css states the reasoning
 * for: there is nothing here that needs one.
 *
 * `25-184`: dark-first three-state cascade, the same shape `ago-landing/styles.css` and
 * `ago-console/src/design/tokens.css` both use - bare `:root` is the dark palette (already was, and
 * stays the source of truth), `:root[data-theme="light"]` is the manual override, and the
 * `prefers-color-scheme` block now guards itself with `:not([data-theme="dark"])` so an explicit
 * dark choice can win over a light OS setting too, not just the reverse. Same light values as
 * before, just no longer the only way to reach them - see `theme.js` for what writes the attribute.
