This example demonstrates how basic SVG shapes—circles, rectangles, lines, and paths—are styled using CSS, with explicit fills, strokes, and group transformations. The SVG markup defines a 960×500 canvas, scaled by 1.5, containing shapes with hardcoded coordinates. CSS rules in `styles.css` apply stroke styling to line elements via a `.lines` class and set a round stroke-linejoin on paths, while the body’s margin and overflow are reset. No JavaScript or data is involved; the rendering relies solely on SVG’s native presentation attributes and external stylesheets.
