seaswalker/spring-analysis ? reverse-engineered prompt

Build me a simple Spring source code study site that organizes my reading notes in one place. I want it to have a home page with clear links to sections for Spring core, aop, context, task, transaction, mvc, and a small Guava cache note too. Each section should open a clean readable article page for my notes, with a nice table of contents and easy navigation between sections so I can study the framework step by step.

Keep the look simple and focused on reading, not a fancy product app. It should be easy to add or edit notes later, and the pages should work well on both desktop and mobile. If you need to check current docs or best practices while building it, go ahead and look them up online.
