+> With TypeScript 6+, when a `tsconfig.json` is present, `rootDir` defaults to `.`. If your config uses `outDir` and includes sources under `src`, set `"rootDir": "./src"` explicitly to avoid TS5011.

 This pre-`tsc` step rewrites globals-only (keeps import/export syntax) so the TypeScript checker sees already-rewritten sources; runtime semantics still match the target build.

 - Skips lowering when `module` or `exports` are shadowed at module scope to avoid mis-compilation.
 - Throws when encountering `with` statements or unshadowed `eval` to avoid unsound rewrites.
 - Deprecated CJS features (`require.extensions`, `module.parent`, legacy folder-as-module resolution) are left as-is.
