A gallery of 18 pink circular faces, each composed of a salmon-stroked background circle, two eyes, and a mouth, renders as a static grid of SVG elements. React generates the faces, while D3’s `arc` API creates the mouth path for each. Randomized parameters for eye offset, eye radius, and mouth dimensions vary the expressions across the faces. The `FaceContainer` component wraps the SVG coordinate system, centering all elements within each 160×160 viewport.
