Eternal Cosmos

Why your app previously showed blank on Hostinger: Standard Hostinger shared hosting environments (Apache/LiteSpeed with PHP) cannot run Node.js daemons or compile React/Vite JSX dynamically in the browser. When raw React or unbundled Vite files were uploaded, the browser received an empty <div id="root"></div> and failed.

How this version fixes it: This application has been completely transformed into a pure, high-performance web package consisting of standard HTML5, CSS3, Vanilla JavaScript, and PHP. It requires zero compilation, zero Node.js daemon, and zero build step on Hostinger.
