memory and main-thread fixes: ray map computed per ray instead of stored, photos take their world snapshot only when the render starts instead of while queued, biome tint blend cached per photo with the biome height in the key (was global, unbounded and stale across photos, worlds and 3d biomes), item definitions cached per id and context with the day only for local_time models, one date per photo for christmas chests and local_time, model chains cut at the depth limit not cached, bake failures logged per photo, no sync chunk loads for end gateway neighbours and spawner display mobs, a broken datapack variant file skips only itself
