This fork of the Blank Slate template serves as a minimal "Hello World" for the VizHub V3 Runtime Environment. It demonstrates the required entry point by exporting a `main` function that receives a `container` DIV and writes styled HTML directly into it. The example sets a large `font-size` of 212 pixels with inline CSS to display the text centered on the page. No external libraries are used; it relies solely on the DOM manipulation to render the static message, making the runtime's hot reloading and widget interaction the focus.
