Diod 0.1.0.45 — Northern Isles: an original Nordic world

- Replace the imported island with original Nordic-inspired geography inside the same 5.12 km playable boundary.
- Explore a mountainous western spine, central woodland, eleven eastern and central freshwater lakes, a low southern island and a rugged western island.
- Start fresh in a safe central meadow, with resources and animal habitats placed for the new world.
- Give inland lakes their own elevations and distinguish freshwater from the surrounding sea. Align the exploration map with the new terrain.
- Replace current-game Kungsholmen branding and remove retired imported geography and its notices from the new package. Original art, audio and engine credits remain.

FRESH WORLD
This release starts a fresh Northern Isles world. Earlier-world inventory, knowledge, buildings and excavations do not carry over. No manual save deletion is needed. New Nordic progress saves normally.

KNOWN LIMITS
- The islands are compressed original landscapes inspired by northern Europe, not accurate country-scale geography. Mountains use the existing terrain rendering system.
- Performance hitches remain; surface water is a two-metre model rather than full three-dimensional cave-fluid simulation. Workers remain dormant and B/G custom design remains retired.
- Intel Mac, physical controllers and Windows/Linux GPU gameplay are not tested.

VALIDATION
Linux: Exported Nordic23 geography, freshwater/sea, spawn, resources, animals, save/reload and mesh checks pass, along with identity, underwater excavation, cave placement, prefab construction, water basin and normal shell. Linux GPU gameplay not tested.
Windows: Windows export, executable icon and numeric version checks pass. Windows GPU gameplay and publisher signing are not validated.
Macos: Apple accepted and stapled the universal package. Exact archive size/SHA, strict all-architecture signature, quarantined Gatekeeper and normal startup shell pass. Exported Nordic23, identity, excavation and cave placement pass. Package audit confirms retired imported geography is absent. Native fresh-world startup, no inherited buildings, physical spawn ground, stable standing, map and reload pass7 on Apple M4 Metal Low160m. Native images inspected; clean exit. Intel Mac and physical controllers untested. Existing performance limitations remain.
