A set of basic SVG shapes—circles, rectangles, lines, and a path—demonstrates vector rendering with inline styling and CSS classes. The example defines a `<g>` scale transform and nested groups to position shapes, using SVG presentation attributes like `fill`, `stroke`, and `stroke-width`. A CSS rule styles the `.lines` group and its path child. This simple gallery piece shows how SVG primitives combine with transforms and cascading styles without any JavaScript libraries.
