/* assets/front/front.css
 * ATHCM — wheel-centric (NEW)
 * - No “Selected Palette” panel
 * - Color Rule is an overlay INSIDE the wheel card (top-left)
 * - Kuler sliders/swatches render in the SAME wheel card, docked bottom-right
 *   (NO JS moving theme nodes; we style the populated theme where Kuler renders it)
 * - Results remain grouped cards
 *
 * IMPORTANT:
 * - Do NOT hide .colorwheel-theme globally. Kuler renders TWO nodes:
 *   1) an empty clone: <div class="colorwheel-theme"></div>
 *   2) a populated theme: <div class="colorwheel-theme">...swatches...</div>
 *   We hide ONLY the empty one via :empty.
