Defined in: packages/three-flatland/src/loaders/normalDescriptor.ts:117
Build one flat region per frame rect. Each region inherits descriptor defaults — most sprite sheets don’t need per-frame direction, but individual frames can be overridden by the caller merging custom regions in.
Region-local alpha clamping (applied by the baker) is what keeps adjacent frames from bleeding gradients into each other.
