/**
 * Development/Test fixture seeding. Idempotent: running it twice must not
 * duplicate anything. Never run against production data.
 *
 * Fixture matrix (documented in apps/web/e2e/README.md):
 *   fixture-admin    active, Site Admin
 *   fixture-user     active, regular account
 *   fixture-pending  registered but e-mail not verified
 *
 * All fixture accounts share the password below — they exist only on
 * dev machines and disposable CI/Test databases. On shared stages
 * (test/int), set FIXTURE_ADMIN_PASSWORD / FIXTURE_USER_PASSWORD to give
 * those two accounts non-public passwords.
 *
 * Content fixtures (issue #32): a shared pond owned by fixture-user with
 * two pages — "Every Element" (every editor schema node/mark, #24, loaded
 * from the checked-in `fixtures/content-page.yjs`; regenerate via
 * `pnpm --filter @dorfteich/api fixtures:regenerate` after editing
 * `fixtures/content-page.md`) and "Fixture Image" (one real, servable
 * uploaded image) — for the content regression pack and manual QA.
