Summary

Preserve raw MagicaVoxel sources and render eligible baked .vox meshes through a voxel slice renderer that uses three axis hosts plus absolutely positioned <b> brush rectangles.
Port the voxcss mergeVoxels: "3d" slice planner into core and reuse it from the vanilla renderer, while keeping polygon fallback for dynamic lighting, shadows, stable DOM, and edited geometry.
Remove the gallery VOX slices toggle path, update docs/AGENTS, and keep the gallery using the new default voxel fast path.
