A broadcast overlay built from <b>multiple files</b> — SVG layers + a GSAP timeline + a JSON config + the
preview that stitches them together. Describe a change, and patchling rewrites <i>all</i> of them (adding or
removing files as needed); the loop re-renders live on the right. <b>Export</b> a standalone transparent
