/* gyrum.ai homepage v2 — canon-layered stylesheet (warp#20020).
 *
 * Layer order (canon tiering):
 *   0. vendor/tokens.css — @gyrum-labs/tokens v2.1.3, the ONLY source of
 *      colour/spacing/radius/type. Loaded before this file via <link>.
 *   1. base — element defaults consuming tokens.
 *   2. atoms — gy-* canon classes (vendor/canon-classes.css, warp-owned
 *      internals) + .skip-link, .eyebrow, .product (layout only).
 *   3. sections — nav/hero/receipts/case/how/paper/products/closing/footer.
 *
 * Rule: no raw hex anywhere in this file. Every visual value in THIS file
 * resolves to a canon token (Home palette: --home-*); the vendored canon
 * files carry their own definitions/metrics by design (see vendor/).
