NiketF/ebook_generator ? reverse-engineered prompt

Build me a simple web app that helps HR and recruitment people generate a professional career guide for any job role they type in.

I want to enter something like Data Scientist, click a button, and have the app create a polished long form e book style report in HTML that looks ready to share with clients or new hires. It should include a table of contents, role overview, key skills, industry insights, salary or market style guidance, a multi year learning roadmap, and other useful sections that make it feel like a complete guide.

Make the page easy to use, with a clean input area, a generate button, a preview of the finished HTML, and a way to download the result. Use the Gemini API for the content generation, and keep the formatting professional with embedded styling so it looks good right away.

If you need to check the latest API or Streamlit setup details, look them up online.
