sagarchry0777/dsa-handbook ? reverse-engineered prompt

Build me a clean study website for DSA interview prep that feels like a practical handbook, not a textbook.

I want the site to organize problems by pattern, with each pattern page showing how to recognize the pattern, a simple template to remember, a ladder of problems from easy to hard, worked examples, common mistakes, and a few “same problem in disguise” notes. Add a roadmap page with 2, 8, and 16 week study plans, plus a “how to practice” page with timeboxing and review reminders for day 1, 7, and 30.

It should also support writing new notes in markdown, generating the next order automatically, and publishing only when the content builds cleanly and all internal links work. A live preview would be great, and if you need to check anything, look up the current docs online. Keep it simple, readable, and focused on helping someone prepare for interviews after work.
