/**
 * Extracts a representative solid color from a color or gradient declaration.
 *
 * When a gradient is provided, the first declared stop is returned. Plain colors are returned unchanged,
 * which makes this useful for fallbacks in APIs that only accept a single fill color.
 *
 * @param color Solid color string or gradient declaration.
 * @returns A solid CSS color string suitable for non-gradient render paths.
