kilicdev/tiktok-auto-post ? reverse-engineered prompt

Build me a Node.js app that uses a real browser to automatically grab video episodes from a source site and post them to TikTok for me.

It should open a normal Chrome session, keep me logged in, browse the source catalog, pick the next episode that has not been posted yet, download it to my computer, then upload it to TikTok with a caption based on the source description. After a successful post, save that episode so it never gets uploaded again.

I also want it to run once for testing or keep running on a schedule, with a short retry if something fails. If a step breaks, save a screenshot and page dump so I can figure out what happened. Make it easy to change the source URL, the TikTok upload page, and the timing settings from one config file. If you need to check current browser automation docs online, go ahead.
