  , with unit tests asserting the
  redirect destination.

+/**
+ * Unit tests for the Lineage landing page content (task 08).
+ *
+ * Mirrors the `page-head-meta.ts` / `nav-config.ts` pattern: assert against
+ * pure constants exported from `landing-content.ts` (no solid-js / router /
+ * DOM). This covers the task-08 acceptance matrix that's structurally
+ * verifiable without rendering:
+ *  - App Store link is present and correct
+ *  - Google Play / downloads link targets the subdomain `/downloads` path
+ *    (public browser path, NOT the vercel-rewritten `/lineage/downloads`)
+ *  - Feature highlights cover: dark fantasy, mobile, remote saves, PvP
+ *  - PageHead base title + description (suffix is added by PageHead, task 02)
+ *  - Legacy `/marketing/life-and-lineage` redirect target points at the
+ *    Lineage subdomain.
+ *
+ * The PageHead title-suffix + canonical derivation for the lineage site is
+ * already covered by `src/components/PageHead.test.ts`; these tests assert
+ * the *inputs* the page passes to PageHead.
