- GROUND_MOSAIC_SIZE 9 -> 16 (16x16 = 256 tiles, covers 16 world
units instead of 9 — wider safety margin at the mosaic edge)
- Fog: tGround / 30 -> tGround / 12 with full mix (was 75% mix)
so distant ground fully fades to sky instead of staying visible
with wrong UVs (which was the source of the striped look)
- Result: visible ground content matches mosaic; far ground
cleanly fades to sky, close ground shows clear satellite tiles
