/**
 * Profile fixtures for the v2 → v1 categories migration tests.
 *
 * These fixtures are intentionally loose — they match the minimal shapes
 * consumed by categoryMappingService.ProfileData and the broader migration
 * test helpers (budget/categorization regression). They are *not* a mock of
 * the full Tauri DB layer; tests that need DB access still mock `getDb`.
 *
 * Three flavours are provided:
 *   - `makeV2Profile()`           realistic v2-seeded profile (~30 cats)
 *   - `makeV1Profile()`           same user data but already on v1 taxonomy
 *   - `makeV2ProfileWithCustom()` v2 profile with 3 user-created categories
