/*
 * Docs homepage, in the style of the documentation.ai website. Loads after
 * styles/docs-theme.css and reads its tokens (--da-*) and fonts.
 *
 * Every rule is scoped to the page that renders snippets/docs-home.jsx (its
 * root carries `dh-home`), so the other docs pages get the theme alone. The
 * headings and the "Explore the docs" grid stay plain MDX, editable in the web
 * editor; the painted steps and the migration row are the two snippets, and
 * this file styles all of it.
 *
 * The page, top to bottom:
 *   1. Title and description (frontmatter).
 *   2. "Start here": four numbered steps, each titled on a painting with
 *      its description below (docs-home.jsx).
 *   3. "Explore the docs": the Columns block, a plain lattice.
 *   4. The migration row: copy beside a painting (docs-home-migrate.jsx).
 *
 * The paintings are the website's own (public/img/scenery there, listed in
 * src/lib/scenery.ts), loaded from documentation.ai so both sites show one
 * set. Each veil follows the website's rule: black at 1 - 0.34 / luma, a touch
 * heavier in the middle (1.15x) and lighter at the edges (0.85x), so every
 * painting comes out equally bright; a step darker again in the dark theme.
