1//! `celestial/chunk-bake` — Phase-4 compute dispatch that bakes per-chunk
2//! colour + normal detail tiles into the atlas textures. One thread per tile
3//! texel (`realize_count * tile_res²`). Runs after `chunk-realize`; reads the
4//! same uploaded descriptors and writes the colour/normal atlases the surface
5//! fragment shader samples.
