You should have a hosted site for this - It is entirely frontend - right?

almost! the editor/compositor is fully browser side, but the server is doing real work: project.json lives on disk (thats the whole point, any agent or script can edit it and fs.watch + sse hot reloads the ui), plus ffmpeg for the final export encode. so it needs the local server for the actual workflow.

a hosted demo mode is a good idea though, project in localstorage + sample footage + mediarecorder export would let people feel the editor without cloning. the one thing it cant show is the main trick, watching an external agent rebuild your timeline live, since theres no local file for it to edit. might do a stripped demo build if theres interest
