sqm2050/wiki ? reverse-engineered prompt

Build me a simple personal wiki and notes site that lets me organize information by topic like Books, Study, Work, and Projects.

I want it to feel clean and easy to use, with a homepage that shows the main sections and lets me click into each one to read the pages inside. The content should work well with markdown so I can keep writing notes in plain text and have them display nicely. If it makes sense, include a basic search so I can find things quickly, and make it easy to add or edit pages without a lot of setup.

Please keep it lightweight and practical, more like a private knowledge base than a fancy app. Use the existing folder structure as the source of truth if that helps, and look up current docs online if you need to.
