atlasCatalogFields(
atlas,pagePath):Pick<CatalogEntry,"atlas"|"frame"|"uv">
Defined in: asset/Catalog.ts:44
Derive a CatalogEntry’s atlas fields from a cook-manifest atlas record.
Frame pixels are image-space (y from the page TOP); uv is emitted for
flipY-uploaded textures (v origin = image bottom), matching the
Sprite/UIVisual uvOffset/uvScale convention. pagePath is the page’s
fetch identity — the same string every frame of the page shares, so texture
loading can collapse them onto one GPU texture.
