/**
 * Content regression pack (issue #32) — the one M2 e2e suite that runs in
 * CI (job `auth-e2e`, `.gitea/workflows/ci.yml` — a second step there,
 * reusing the same built+seeded stack rather than a separate job), against
 * a local prod build seeded exactly like Test/Int. Covers page lifecycle, editor
 * basics, image paste, Markdown round-trip, and trash: enough to catch a
 * regression across the whole M2 content model without re-running every
 * edge case already covered by the feature-specific packs (editor/image/
 * link/markdown/trash/sidebar `.spec.ts`), which stay local-only.
 *
 * The Markdown round-trip test is the pack's actual regression pin: it
 * compares the seeded "Every Element" fixture page's exported Markdown
 * byte-for-byte against `content-page.md` (checked in next to the seed
 * script, `apps/api/prisma/fixtures/`, regenerated via
 * `pnpm --filter @dorfteich/api fixtures:regenerate`). The export endpoint
 * serves the *cached* `page_content_cache.markdown` (refreshed by the seed
 * script/state saves, not derived live on every request, #23/#30) — so a
 * schema/serializer change only surfaces here once the seed has re-run
 * against it, which is exactly what CI does on every run (build → migrate
 * → seed → this pack). Verified during development: temporarily changed
 * `docToMarkdown`'s heading serializer, rebuilt `packages/shared`, re-ran
 * `db:seed`, and confirmed this assertion failed with the mutated output;
 * reverted immediately after.
