// =============================================================================
// Overworld Data Layer
// =============================================================================
//
// ARCHITECTURE OVERVIEW:
// ----------------------
// The Overworld class is the central data manager for A Link to the Past's
// overworld system. It handles 160 map screens across three worlds:
//   - Light World: Maps 0x00-0x3F (64 maps)
//   - Dark World: Maps 0x40-0x7F (64 maps)
//   - Special World: Maps 0x80-0x9F (32 maps, expandable to 0xBF with patches)
//
// DATA ORGANIZATION:
// ------------------
// The overworld uses a hierarchical tile system:
//   - Tile32: 32x32 pixel blocks composed of four Tile16s
//   - Tile16: 16x16 pixel blocks composed of four Tile8s
//   - Tile8: 8x8 pixel base tiles from graphics sheets
//
// Map tile data is stored as arrays of Tile16 IDs in OverworldBlockset:
//   - map_tiles_.light_world: 64 maps of 32x32 tile16 IDs each
//   - map_tiles_.dark_world: 64 maps of 32x32 tile16 IDs each
//   - map_tiles_.special_world: 32+ maps of 32x32 tile16 IDs each
//
// SAVE SYSTEM DOCUMENTATION:
// --------------------------
// The save workflow is controlled by feature flags in OverworldEditor::Save().
// Each component saves independently but some have ordering dependencies.
//
// SAVE ORDER AND DEPENDENCIES:
//
// 1. TILE DEFINITIONS (must be saved first, others depend on these IDs):
//    - CreateTile32Tilemap(): Build tile32 from current tile16 data
//    - SaveMap32Tiles(): Write tile32 definitions to ROM
//    - SaveMap16Tiles(): Write tile16 definitions to ROM
//    - SaveOverworldMaps(): Write compressed map tile data
//
// 2. ENTITIES (independent, can save in any order):
//    - SaveEntrances(): Entrance warps to underworld
//    - SaveExits(): Exit points returning from underworld
//    - SaveItems(): Hidden items on overworld
//
// 3. PROPERTIES (independent, can save in any order):
//    - SaveMapProperties(): Graphics, palettes, messages per area
//    - SaveMusic(): Music IDs per area and game state
//    - SaveAreaSizes(): Area size enum for v3+ ROMs
//
// 4. CUSTOM FEATURES (v2+/v3+ only):
//    - SaveCustomOverworldASM(): Custom feature enable flags
//    - SaveAreaSpecificBGColors(): Per-area background colors (v2+)
//    - SaveMapOverlays(): Interactive overlay data
//
// TESTING SAVE FUNCTIONALITY:
// ---------------------------
// To test individual save components:
//   1. Enable only one feature flag at a time in core::FeatureFlags
//   2. Make changes to that component in the editor
//   3. Save ROM and verify changes in an emulator
//   4. Check for corruption by loading saved ROM back into editor
//
// Round-trip testing:
//   1. Load vanilla ROM
//   2. Make changes to all components
//   3. Save ROM
//   4. Close and reopen ROM
//   5. Verify all changes persisted correctly
//
// See app/editor/overworld/README.md for complete workflow documentation.
