// NOTE: The plain `replace` / `replace_all` unit tests were moved to
// `packages/rolldown/tests/magic-string/rolldown-magic-string.test.ts` so they
// exercise the JS binding's UTF-16 -> UTF-8 conversion. The sourcemap snapshot
// tests below stay here because they rely on `insta` + `SourcemapVisualizer`.
