Hello HTML
A minimalist SVG drawing of a smiley face uses two black-outlined circles for eyes atop a larger yellow circle for the head, all rendered inside a 960×500 viewport. The page loads React 17.0.2 from a CDN and logs the global `React` object to the console, demonstrating integration. Static SVG elements define the shapes with explicit coordinates, while CSS sets margin and overflow properties for full-window display.
