This is a straightforward wrapper around Chrome DevTools Protocol for capturing full-page screenshots without pulling in extra dependencies. You point it at a URL and get back a complete vertical capture, which beats stitching together viewport scrolls manually. Handy when you need to document a landing page for a portfolio, archive a design mockup, or grab evidence for a QA report. The zero-dependency claim matters if you're running this in CI or serverless environments where you want to keep the footprint small. It does one thing and the implementation is simple enough that you can probably read through the upstream repo in ten minutes if you need to understand how it talks to Chrome.
