/*
 * ade-ops landing home — family design kit.
 * Hand-ported accent + layout to mirror the ade-catalog Vercel landing
 * (Tailwind sky palette) without pulling the Tailwind CDN into the docs build.
 * Scoped to the .ao-* classes emitted by overrides/home.html, so it never
 * touches the rest of the MkDocs Material docs pages. Sections use fixed
 * colours (light base + one dark hero) so the landing looks identical under
 * both the default and slate palettes, like the catalog page.
