/**
 * The world.json `assets[]` record for a file a creator uploaded, kind by kind.
 *
 * Kept pure — inputs in, a plain object out — so the shape each kind writes is unit-tested
 * without a project on disk, and so `add.ts` stays about the order of operations (classify, read,
 * upload, bake, write) rather than about which fields go where.
 *
 * Every shape mirrors what the Creator's Assets tab writes for the same file
 * (`useAssetsEditor.ts` `handleFileUpload`, `assetsGlbKeepImport.ts`), including `production`:
 * `uploaded` is the one provenance only the uploading side can know — the engine's voxelize
 * handler stamps `generated` because it sees the same GLB whether a person or a generator made it,
 * and the Creator overwrites that too.
