The biggest problem I see is that you need to search for videos. If this is going to work you need a YouTube like home page with videos on it and a different webpage talking about the tech. Using a search page to find videos instead of being presented with one is a non starter.
Honestly, it was about 4-6 hours of hands on keyboard. Bout a day and a half overall with a handful of smaller tweaks/bugfixes since then. I am definitely planning on writing about it. tl;dr this was sort of glorified vibe-coding and intentionally so in order to really see what 4.8 was capable of. But I do have some interesting observations that I made along the way that I'm going to go into more detail about.
