A standalone SVG demonstrates fundamental shape primitives inside a single `<svg>` viewport. A yellow rectangle animates its corner radius from zero to a full pill shape and back, while two circles and an ellipse form a static face-like composition. The entire group moves along a rectangular path using the native SVG `<animateMotion>` element, with the rectangle’s shape change driven by `<animate>`. The page uses no external libraries, relying entirely on inline SVG markup and the browser’s built-in animation APIs.
