```

## Test Structure

## GitHub Actions

The CI pipeline runs on every pull request via GitHub Actions with two separate jobs:

### Lint Job

1. Sets up Node.js 18
2. Installs dependencies
3. Runs linting (Prettier + TypeScript compilation)

### Test Job

1. Sets up Node.js 18
2. Installs dependencies
3. Executes the test suite

Both jobs run in parallel for faster feedback. The workflow file is located at `.github/workflows/ci.yml`.
