The item model harness ran out of memory, so it now streams both outputs and
looks Horizon's rows up by offset. With the vanilla side no longer crashing on
swap-animation lookups (properties now come from the baked set), on armour
(trim sprites are generated by the items atlas's paletted_permutations source
once SpriteSources is bootstrapped) or on compasses (item tags are bound from
the data pack), 197,000 more stacks were compared and 121,841 differed.
Horizon now composes transformations as JOML 1.10.9 does: rotationXYZ and
axis-angle quaternions with cosFromSin, and Matrix4f operations that take the
identity, translation, affine or generic path by matrix properties, with
unfused a * b + c. Float RGB tint constants are scaled by 255, the shulker box
renderer always encodes its texture, and a new palette module ports
PalettedPermutations and PaletteMapping so trim sprites exist on the Horizon
side too.
196,290 resolved stacks match; 2,582 cases are still rejected by vanilla's
stand-in client and not compared.

Work in progress on vanilla's item model pipeline in horizon-assets: definition parsing, resolution, generated model baking, special renderers and a differential harness against a Java oracle.
