The launcher prepares a version in-process when it ships the preparer sources
the launcher was built with, with the version's own horizon-prepare when they
differ, and with the Python script only for versions made before it. Release
folders ship horizon-prepare and its sources; resources are reused between
versions with the same preparer. The game's messages, PLAY.txt, the docs and
release builds name horizon-prepare, and tools/prepare_native_client.py is a
wrapper of it for the development tools.

The client random-ticked every section with a non-air block, drawing
getBlockRandomPos positions vanilla never draws. It now ticks a section only
when its palette holds a randomly ticking state, as
LevelChunkSection.isRandomlyTicking does (lava counts through LiquidBlock).

The section mesher blended biome colours over quart cells at the section's
mid-height. It now follows ClientLevel.calculateBlockTint: each tinted block
averages the colours of the biomes BiomeManager picks (the eight-corner
zoom with the client's hashed seed) over the biomeBlendRadius square at the
block's own height, computed lazily per layer and column. The ao and
cutoutLeaves options are honoured too: flat lighting, skipped faces between
opaque leaves and a vertex layer flag that makes the terrain shader ignore
leaf alpha.
The section mesh parity gate gained biome-blend scenes (random zoom seeds,
radii 0 to 7, all 67 biomes, real Biome colour resolvers through a
BiomeManager in the Java oracle) and option scenes; all 1.0M quads of the 112
scenes match the client.
