HemantCrafts/podcast-generator ? reverse-engineered prompt

Build me a small web app that turns a blog post URL into a podcast episode.

I want to paste in a blog link, have the app pull out the main content, summarize it, and then generate audio with a natural sounding voice. It should have a simple password protected page so only I can use it, and it should let me download or listen to the finished MP3.

I also want a second mode that makes it feel like a real interview, with a researcher, a host, and an expert having a back and forth conversation based on the article. Each speaker should use a different voice, and the voices should be combined into one audio file.

Please make it easy to run locally and with Docker, and use environment variables for the API keys. If anything needs current setup details, look them up online and wire it up the right way.
