Action Summary

ZPL Regression Gate is a GitHub Action that automates the detection of unintended changes in Zebra Programming Language (ZPL) label formats. It compares approved semantic and PNG baselines with current renderings to identify discrepancies, ensuring consistent and expected label outputs before they reach a warehouse or printer queue. The action provides actionable feedback on changed fields, barcodes, coordinates, font commands, dimensions, diagnostics, or rendered pixels, enabling developers to catch and fix issues early in the development cycle.

What’s Changed

• Adds reproducible demo inputs and a structured example report.
• Improves npm description and exact-intent keywords for ZPL and Zebra label testing.
• Keeps the clean npm 12 installation introduced in v0.2.0.
