 90            ## What?
 91
 92            Replaces `public/assets/demo.gif` with a freshly recorded VHS run.
 93
 94            ## Why?
 95
 96            Keeps the demo GIF aligned with the latest release so README and docs reflect current behaviour. Generated automatically by the Update Demo VHS workflow.
