Weltkarte: tile-basiertes Rendering, Hires-Chunks, 5 Zoom-Stufen

Browse Source 
- Durchschnittliche Kachel-Farben (terrainColorMap, 2048px) als Basis für Low-Res-Ansicht
- Bilineares Splatmap-Blending (blendTileAvgColors) statt Nearest-Neighbor
- Chunk-basierte Hires-Karte (8192px, 256 Chunks à 512px) auf Disk gecacht
- Zoom-Stufen 0–2: Overview-Bild; Stufen 3–4: Hires-Chunks per LRU-Cache
- 5 geometrisch verteilte Zoom-Stufen (Fit-All bis 0,25m/Pixel)
- Klippen-Erkennung per Steigungswinkel (1,5m Sampling-Distanz, harter 30°-Schwellwert)
- Leichter Box-Blur (Radius 2) über Terrain-Layer
- Wasserfarbe in Hires-Chunks vereinheitlicht (WATER_COLOR)
- Kein Hillshading
