ayqshi/mini. — reverse-engineered prompt

Build me a clean little browser app called mini. that helps developers quickly shrink front end code without needing a server.

I want a polished desktop first page where someone can paste HTML, CSS, JavaScript, or JSON into an input editor and instantly get the minified output on the other side. Include a language selector, live minification toggle, paste and copy buttons, character counts, and a clear savings indicator so users can see how much smaller the code became.

Add simple settings for stripping comments, collapsing whitespace, and optionally mangling JavaScript variables. JavaScript minification should use Terser, CSS should use clean css, and everything should run fully in the browser. Keep the design minimal, professional, fast, and distraction free, with smooth small animations and a nice monospace editor feel. Use HTML, Tailwind CSS, and vanilla JavaScript in a simple static project.
