Rivencraft 26.3 beta 1.0.1.39-beta.1

This beta adds Cave terrain to authored Ages on Minecraft 26.3.

• Bind Descriptive Books with the Cave terrain page and Cave or Nether biome pages, including supported multi-biome distributions.
• Cave Ages use the cave noise shape but remain dry by default. Newly generated chunks no longer flood below the vanilla cave sea level.
• Cave travel searches from Y=64 downward for dry, properly footed space instead of landing on the cave roof or underwater.
• Expanded dedicated-server checks for Cave creation, biome distribution, and persistence after restart.

The player verified the Cave and safe-landing changes in game. Existing generated chunks are not drained or regenerated. A future Flooded page will provide an authored water level; see issue #107.

This 26.3 port is still experimental and does not yet include all features of the separate Minecraft 1.21.1 version. Use a test world and keep a backup. Minecraft 1.21.1 saves are not supported by this beta.

Requires Minecraft 26.3, NeoForge 26.3.0.99 or a compatible 26.3 build, and Java 25.
