Explanation

GitHub Actions supports environment variable scoping at three levels: workflow-level (env: at the top of the workflow file, available to all jobs and steps), job-level (env: under a job definition, available to all steps in that job), and step-level (env: under a specific step, available only to that single step). The step is the smallest scope - an environment variable defined at the step level cannot be accessed by other steps or jobs. This scoping model allows precise control over variable visibility.
