+ * @file dungeon_rendering_test.cc
+ * @brief Integration tests for dungeon rendering with mock ROM data
+ *
+ * ============================================================================
+ * DEPRECATED - DO NOT USE - November 2025
+ * ============================================================================
+ *
+ * This file is DEPRECATED and excluded from the build. It duplicates coverage
+ * already provided by dungeon_object_rendering_tests.cc but uses mock ROM data
+ * instead of the proper TestRomManager fixture.
+ *
+ * REPLACEMENT:
+ * - Use test/integration/zelda3/dungeon_object_rendering_tests.cc instead
+ *
+ * The replacement file provides:
+ * - Same test scenarios (basic drawing, multi-layer, boundaries, error handling)
+ * - Proper TestRomManager::BoundRomTest fixture for ROM access
+ * - Cleaner test organization following project standards
+ *
+ * This file is kept for reference only.
+ * ============================================================================
