CSS minification

Removes whitespace, comments, and redundant characters from CSS to reduce file size. A minified CSS file loads faster and reduces bandwidth cost. For production, CSS is typically minified as part of the build pipeline (webpack, Vite, esbuild) — this tool is for quick manual minification or understanding what a bundler produces.
