- Introduced `test_scenery_brick_preview.gd` to validate focused placement and CPU draw-cost for large brick walls. - Added `test_scenery_surface_cache.gd` to assess texture budget, visual equivalence, and cache invalidation. - Created `test_scenery_surface_preview.gd` to evaluate adaptive preview selection and placement behavior. - Implemented various helper functions to measure drawing performance and validate expected behaviors during tests. - Added unique identifiers for new test files to ensure proper tracking and management.
