Welcome to Documentation

This is a responsive documentation layout that adapts seamlessly to different screen sizes. The sidebar contains navigation links that organize the content, and the main content area displays the documentation text. The layout automatically stacks on mobile devices, remains perfectly sized on tablets, and displays side-by-side on desktop screens without any horizontal overflow.

All styling is inlined, and the page requires no build process or external resources. It renders correctly in any modern browser when opened directly from the file system.
