HTML Starter
This example displays basic SVG shapes—two circles and two rectangles—on a blank canvas. It demonstrates how to create a minimal HTML page with inline SVG markup, using the `<svg>`, `<circle>`, and `<rect>` elements. The first pair of shapes uses default black fills, while the second pair specifies explicit colors via the `fill` attribute. The page relies on plain HTML and CSS, with no JavaScript libraries or external data sources. The `index.css` file sets the body to hide overflow, ensuring the 960×500 SVG renders edge-to-edge.
