+ * Base test case for Phase 1 imitation harness tests.

+ * database transaction so every test starts from a clean, known state.
+ *
+ * Usage:
+ *   Extend this class (PHPUnit-style) or include the trait equivalents
+ *   in Pest tests. Pest tests should prefer:
+ *
+ *     uses(DatabaseTransactions::class, SharesSupplierPdo::class);
+ *     beforeEach(fn () => (new ImitationTestCase())->seedReferenceData());
+ *
+ * Schema dependencies (exact columns verified against db/schema.sql):
+ *   pricing_tiers: id, tier_no (1..7), leads_in_tier, price_per_lead_kopecks,
+ *                  is_active, effective_from, created_at, updated_at
+ *   suppliers:     id, code, name, accepts_types (varchar[]), cost_rub,
+ *                  channel, quality_score, is_active, sort_order, created_at
+ *
+ * Note: suppliers (b1/b2/b3/direct) are seeded via the initial schema
+ * migration and delta-migrations — they are expected to already exist in
+ * the test database. This case does NOT re-seed suppliers; it only verifies
+ * that at least one supplier row with code='b1' is present and seeds
+ * pricing_tiers via PricingTierSeeder.
+ *
+ * phone_ranges are NOT seeded globally. Tests that exercise the region-
+ * resolution cascade (Россвязь lookup) should call seedPhoneRange() directly
+ * for the specific range their scenario requires.
