summary
Clear, runnable recipe for GitHub Actions: a minimal workflow_dispatch that checks out code, defines job IDs, uses a self-hosted composite action, wires inputs/outputs, and echoes values; demo uses GitHub runners, platform.sh to spin PR preview URLs, and BackstopJS for visual regression. The demo reports 24 passing and 1 failing screenshot, uploads diffs as an artifact, and returns a failing status so CI reflects the regression.
