## Summary - add native Turbopack support for `import.meta.env.DEV`, `PROD`, `MODE`, `BASE_URL`, and `SSR` - statically analyze built-in values for dead-code elimination while exposing the complete runtime object - derive `BASE_URL` from the Next.js `basePath` and include Vite-compatible trailing-slash formatting - add TypeScript declarations, focused execution and Next.js integration coverage, and Vite migration documentation ## Verification - `cargo fmt --all -- --check` - `cargo nextest run -p turbopack-tests -E 'test(import_meta_env)'` - `pnpm build-all` - `pnpm --filter=next types` - `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-dev-turbo test/e2e/import-meta-env/import-meta-env.test.ts` - `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-start-turbo test/e2e/import-meta-env/import-meta-env.test.ts` <!-- NEXT_JS_LLM -->
