+  `"react-jsx"` selects the production automatic runtime (`jsx`/`jsxs` from `<source>/jsx-runtime`) and `"react-jsxdev"`
+  selects the development runtime (`jsxDEV` from `<source>/jsx-dev-runtime`), matching TypeScript and esbuild. Use
+  `"react-jsxdev"` during development if you want the `jsxDEV` entry point.
+
+Prior to Bun 1.4, `"react-jsx"` behaved like `"react-jsxdev"` and emitted the development runtime.
