yourls/yourls ? reverse-engineered prompt

Build me a self hosted URL shortener like YOURLS that I can run on my own server with PHP. I want an easy web admin area where I can add long links, create custom short links, edit or delete them, and see basic stats like click counts and referrers. It should feel simple for a small team to use, but still be powerful enough to extend with plugins and custom features later. Please make sure the short links redirect fast, and that there is an API so I can create and manage links from other tools too. Include the usual setup files and a clean default landing page, plus a way to protect the admin area with login. If you need to check current docs or examples online, do that. Focus on making it work nicely out of the box and keep the code organized so it is easy to maintain.
