This example demonstrates basic SVG shape rendering and CSS styling within an HTML page. It displays a single heading element, "Hello", whose color is defined both by a CSS rule in the document head and an inline style attribute, with the inline style taking precedence and rendering the text in red. The code uses the standard HTML5 `<h1>` tag and the SVG-capable `<svg>` container, though no explicit SVG shapes are drawn. The rendering approach relies on native browser HTML parsing and CSS cascade rules.
