gmartin-data/notebooklm-prompts ? reverse-engineered prompt

Build me a clean, easy to browse NotebookLM prompt library that helps people find the right prompt template, copy it, and customize the placeholders like [LIKE THIS].

I want it organized by category, with a simple index of all prompts, short descriptions, difficulty labels, and a way to open each template in a readable page or markdown view. It should feel useful for data engineering and study or productivity use cases, and include the special cinematic video overview prompts too.

Please make it easy to add new templates later, and keep the content focused on practical prompts that are grounded in source materials. If there is a good way to search or filter by category and difficulty, add that too. Use the existing docs and templates in the repo as the source of truth, and look up current docs online if you need to.
