/**
 * What a project DECLARES about its art style: `artStyle` at the top level of `src/work/game.json`,
 * `voxel` or `low-poly`, absent meaning `voxel` — every game made before the field existed.
 *
 * One reader, the `platform-declaration.ts` shape, because six commands act on the same field
 * and must never disagree about it: `cover` and `reference make` choose their prompt lead by it,
 * `assets add` and `generate model|prop|character` choose whether a mesh is kept or voxelized,
 * and `judge` uses it as the art direction when GAME-DESIGN.md has no heading for one.
 *
 * Best effort throughout: a missing or unreadable file means "declares nothing" (voxel), never
 * an error. A value that is present but not one of the two lands in `rejected` so the caller can
 * say so once — a typo'd `"lowpoly"` silently voxelizing a Blender level is the failure this
 * exists to make visible.
