- Extend DeletionForm with product discriminator and configurable cooldown cookie
- Extract env-free deletion email helpers into deletion-email.ts with Lineage/Nessa branding
- Make misc.sendDeletionRequestEmail mutation product-aware (subject, html content, cookie)
- Replace legacy /deletion/life-and-lineage page with 308 redirect to lineage subdomain
- Add Lineage and Nessa subdomain deletion route modules with shared content components
- Add Lineage downloads route modules with shared content
- Update privacy policy deletion link to lineage subdomain

+/**
+ * Regression test for the unified `freno.me/downloads` page (task 11).
+ *
+ * Task 11's acceptance criteria require that the unified downloads page is
+ * UNCHANGED — it keeps listing all five products (InputHalo, Gaze, Life and
+ * Lineage, Cork, Shapes with Abigail) with the original asset keys + store
+ * links. Because the page is a SolidJS component (DOM render not configured
+ * under `bun:test`), this is a STATIC SOURCE AUDIT — the same pattern the
+ * p8-001 / p8-008 `misc.test.ts` regression tests use.
+ *
+ * Audits `src/routes/downloads.tsx` for:
+ *  - All five product labels present (no removal / rename).
+ *  - The Lineage APK asset key (`"lineage"`) is still wired to the download
+ *    button — the per-subdomain `lineage.freno.me/downloads` page MUST serve
+ *    the byte-identical APK, which requires the same S3 asset key.
+ *  - The Life and Lineage App Store link is intact.
+ *  - No accidental deletion of the other products' sections.
