 * ai-gagement.com — the coming-soon page and the two legal pages (05-screens/25-website.md, AIG-324).
 *
 * Every value comes from the D3 token files, linked rather than copied (`site/tokens` points at
 * frontend/src/styles/d3/tokens/), so the site and the app cannot drift. A raw value names the
 * property it is excused for, in the same `--d3-allow-*` form the app uses, and
 * frontend/src/styles/d3/no-raw-values.test.ts holds this file to it.
 *
 * Absolute paths throughout: CloudFront answers an unknown path with /index.html, which must
 * still find its stylesheet from any depth.
