  // A solution file: it builds nothing itself and only points at the real
  // projects. It used to carry the compilerOptions directly with no `include`,
  // which made `tsc -b` compile every .ts file in the repository as one project
  // and emit .js/.d.ts next to the sources - overriding each package's own
  // `outDir`, and leaving generated files in src/ that then got committed.
  // Shared options now live in tsconfig.base.json, which each package extends.
