pubgo223344-glitch/crispy-carnival ? reverse-engineered prompt

Build me a clean Java project that’s ready to run and easy to extend.

I want a simple, well organized app with a basic working starter implementation, sensible project setup, and enough structure that I can add features later without fighting the code. Please make sure it builds with Gradle, includes whatever standard files are needed to run from the command line, and uses clear naming and comments where they help. If there are any missing details, use current best practices and look up the latest docs online if you need to.

Keep it lightweight and practical, not overengineered. I mainly want a solid starting point that compiles, runs, and feels like a real project instead of an empty skeleton. If there are tests that make sense, add a few simple ones too so I know it works.
