 * IMPORTANT: this is intentionally a <div role="navigation">, not a <nav>.
 * The legacy SKINBALANCE frontend has a global `nav { position:fixed; top:0; ... }`

 * CSS also set bottom, stretching the element over almost the whole viewport.
 * Explicit geometry below is kept defensive as an additional isolation layer.
