Diod v0.1.0.22 — A playground for Earth

- A separate startup choice opens Terrain playground before loading any survival world. The pause menu also offers it after saving.
- Free flight supports adjustable speed, Shift boost, vertical movement and straight-down overview. Terrain streams around the inspection camera.
- Jump to latitude/longitude, hide trees or water, inspect wireframe, copy a location report, or save a screenshot with matching coordinates.
- The global Earth metadata generator is restored for new worlds and default inspection. The unchanged v21 Stockholm dataset remains available for comparison and existing saves.
- Existing worlds keep their terrain and gameplay progress. New Earth games start in separate run folders. No new artificial bunker rock mountain is added.

CONTROLS
Click Fly / right-click to capture mouse; WASD move; Q/E down/up; Shift x8; wheel speed; O overhead; H home; Esc cursor; F12 screenshot and location report.

UPDATING AND SAVES
Close Diod and replace the complete application/folder. Choose Terrain playground from the startup menu to inspect without opening a survival save. Play Diod loads the existing run with unchanged terrain. New global Earth world in Settings creates a separate run; it does not convert an existing regional world. Keep complete save folders.

KNOWN LIMITS
- This adds inspection tools and restores the prior global generator; it does not claim to fix terrain accuracy or graphical quality.
- Global elevation is coarse ETOPO data with procedural detail; GSHHG shores and generalized Natural Earth rivers are not a detailed city reconstruction.
- The v21 regional comparison retains filtered Mapzen elevation and OSM features; water depths remain modeled.
- Flight uses a local planar coordinate frame. Use coordinate jumps for distant Earth locations. Detailed streamed terrain has a bounded draw distance and the horizon is coarser.
- Native Mac/Windows GPU flight, appearance and fresh Mac Gatekeeper assessment remain owner/local testing. The earlier geometry spire has not been reproduced.

VALIDATION
linux: Actual packaged playground checks (25), preserved regional terrain/map/collision/save checks (47) and release identity passed. Flight, overhead, coordinate jump beyond Stockholm, geographic origin consistency and safe scene lifecycle exercised. UI-only 1280x800 preview reviewed; full-world GPU flight/visual acceptance remains owner testing.
windows: Export, native icon groups/sizes and four-part version passed. Shared gameplay/inspection checked in Linux export; native Windows GPU flight and publisher signing remain pending.
macos: Universal bundle export; fresh Developer ID signing, Apple notarization acceptance and stapling completed. Shared inspection checked in Linux export; native Mac GPU flight/appearance and fresh Gatekeeper assessment remain owner/local testing.
