Lithosphere 1.8.1 Performance Addon - New Caves Balanced Fast
Minecraft Forge 1.20.1 | No height cut

DESIGN GOAL
- Preserve Lithosphere 1.8.1's new authored cave system and natural cave entrances.
- Preserve the optimized Surface Lite terrain and feature reductions.
- Avoid the worst overlap: density caves + underground rivers + aquifers + frequent vanilla carvers.

KEPT
- World height 576 / min_y -64.
- Lithosphere 1.8.1 cavern, claustrophobic, connecting and tunnel density caves.
- Lithosphere 1.8.1 density-based natural entrance_caves.
- Continents, mountains, river valleys, coastal cliffs, karst and volcanic systems.
- Surface Lite smoothing and reduced small pools, lava pools, springs, disks and plant patches.

DISABLED OR REDUCED
- Underground-river density branch: disabled.
- Aquifers: disabled; caves are drier and flooded caves are rare/absent.
- Giant ore-vein noise: disabled; ordinary placed ores still generate.
- Vanilla cave_extra_underground carver: disabled.
- Canyon carver: disabled.
- Normal vanilla cave carver: retained at only 0.005 probability for minor variation.

EXPECTED RESULT
- Better and more distinctive caves than the vanilla-cave Surface Lite build.
- Natural surface cave mouths from Lithosphere's new entrance system.
- Slower than the version that disables all Lithosphere density caves, but substantially lighter
  than Lithosphere 1.8.1 with underground rivers, aquifers and the 0.45 extra cave carver together.
- Large-scale surface terrain and 576 world height remain unchanged.

INSTALL
- Use this as the ONLY Lithosphere performance addon.
- Put it ABOVE Lithosphere 1.8.1 in datapack priority.
- Create a new world for comparison; existing chunks do not regenerate.
- Target: Minecraft Forge 1.20.1 only.
