/*
 * The explainer panel, static pages. See docs/guide-panel-standard.md.
 *
 * Every colour is taken from a custom property the host page already defines,
 * with a fallback beside it. That way the panel adopts each mockup's own accent
 * and dual-mode tokens instead of imposing a palette, and it still renders on a
 * page that defines none of them.
