/**
 * FA.UN base styles.
 * Dock curves are drawn with SVG paths (see index.html) because
 * clip-path on the same element erases border-radius.
 * Screen radii stay in sync through --r (outer) and --b (border width).
 * One fixed desktop canvas (#stage 1600x900) is uniformly scaled by index.js,
 * so mobile renders exactly the same layout.
