📝 Walkthrough

Walkthrough

defineVitestProject in src/config.ts now pre-merges test.environment: 'nuxt' into the project config before calling resolveConfig, instead of mutating the resolved config afterward. The app-vitest-workspace example adds a Vitest browser project configuration scoped to *.browser.spec.ts, a browser test file that checks useAppConfig() and NuxtLink, and browser testing devDependencies in package.json.

In `@examples/app-vitest-workspace/app1/test/app.browser.spec.ts`:
- Around line 7-9: The assertion in the useAppConfig test block is checking for
exact key equality with toEqual(['nuxt']), which is brittle because it will fail
if any additional unrelated config keys are added. Instead of checking for exact
equality of all keys, change the expectation to use toContain('nuxt') to assert
only that the 'nuxt' key is present in the returned config object, making the
smoke test more resilient to future config additions.
