/**
 * Regression test for the legacy `/deletion/life-and-lineage` route.
 *
 * The route was converted from a rendered page into a 308 permanent redirect
 * to `lineage.freno.me/deletion`. Because the route file is a SolidStart
 * server module, this is a STATIC SOURCE AUDIT (same pattern as the
 * `misc.test.ts` regression tests) asserting:
 *  - The route exports a `GET` handler (API-route redirect, not a page).
 *  - The response status is 308 (permanent).
 *  - The `Location` header derives from the centralized
 *    `LEGACY_DELETION_REDIRECT_TARGET` constant (not a hardcoded literal), so
 *    the unit test in `deletion-content.test.ts` is the single source of
 *    truth for the destination.
 *  - No page component / DeletionForm import remains (the form moved to
 *    `src/routes/lineage/deletion.tsx`).
