This example demonstrates basic SVG shapes and styling using CSS and inline attributes. It displays circles, rectangles, lines, and a path, with some shapes using explicit `fill` and `stroke` values while others inherit styles from CSS classes. The page renders a single SVG element with a `transform` scale, and a grouped set of shapes applies stroke settings via a `.lines` class. The code uses plain HTML and CSS, with no JavaScript libraries, and includes a React starter reference in the README.
