Capture polished screenshots and an optimized demo GIF/MP4 of a deployed web project and embed them into that project's GitHub README behind an idempotent SHOWCASE marker block. Use whenever the user asks to "add screenshots to a README", "record a demo of <project>", "showcase <project>", "update project images", "make a demo GIF", wants visitors to see what a project looks like without opening the live link, or wants any deployed project to look better on GitHub — even if they don't say "showcase". Works on any live URL; no install needed in the target repo. Generates assets locally and ALWAYS stops for user review before any commit; never pushes on its own.
