/**
 * Unit tests for the Lineage per-subdomain downloads page content (task 11).
 *
 * Mirrors the `landing-content.test.ts` pattern: assert against pure
 * constants exported from `downloads-content.ts` (no solid-js / router /
 * DOM). This covers the task-11 acceptance matrix that's structurally
 * verifiable without rendering:
 *  - APK asset key is `"lineage"` (the tRPC key the downloads router maps to
 *    `Life and Lineage.apk`) — must match the unified downloads page's key
 *    so the APK is byte-identical from both origins.
 *  - App Store link is the canonical Life and Lineage App Store URL.
 *  - PageHead base title + description (suffix appended by PageHead).
 *  - Back-to-home link is the subdomain-relative public browser path.
