// THE SPLITS ARE MOVES (3.29 sweep, part 2).
//
// Each large module that was cut into parts kept its name and its exports, so
// every importer reads exactly what it read before. One block per split, over
// the import graph (tests/helpers/importGraph.ts): every name an importer asks
// the facade for is still exported by it, no part exports a name its family
// does not use, and nothing outside the family reaches into a part.
