Pull Request Cost Check
─────────────────────────

Run cost estimation whenever Bicep files change in a pull request:

Threshold Gate
──────────────────

Fail the workflow if a deployment estimate exceeds a monthly budget threshold:

Delta Comparison Against a Base File
──────────────────────────────────────

Compare the current template against a base branch version and consume the delta output:

Markdown Output for Workflow Summaries
────────────────────────────────────────

Request markdown output when you want to reuse the formatted result in a job summary or downstream step:
