Promo Video Recorder

Produces shareable product-demo videos of a locally running web app without needing a native screen recorder. It opens the app in Playwright's Chromium, overlays a fake animated cursor, applies smooth zoom that focuses on whatever is being clicked (the thing that makes app-store / X promo videos feel premium), then encodes an X-compatible mp4. It can also upload the result to X. The zoom is a real CSS transform: scale() on the page focused at the clicked element, so it's crisp at any resolution and perfectly synced to the action. You script scenes with helpers: h.zoomSel/zoomAt/unzoom (focus zoom), h.tap (move cursor + click ripple, auto-scroll into view), h.typeIn (human-like typing), h.caption/captionHide (on-screen captions), h.waitForSelector (await a real async result), h.download, h.showFile. Music can be auto-generated (calm ambient pad) or a file path. Verify the output with ffprobe + extracted frames before sharing; outward-facing posting waits for user approval.
