 * docs/_shared/charts.css — palette + structure for shared chart primitives
 *
 * Loaded by docs/index.html, docs/insights.html, and the static portal
 * pages. Variables fall back to either the warm-paper public palette,
 * the Archive theme (`html[data-public-theme="archive"]` in
 * `public-theme.css`), or the dark console palette depending on which
 * page mounts the file.
 *
 * Every selector is namespaced under `.chart-` so it can co-exist with
 * existing portal styles without collision.
