   Các trang app shell đặt `h-screen overflow-hidden` trên body, nhưng `html`
   vẫn là scroll container nên một số trang vẫn cuộn ngang được ở viewport hẹp
   (iot-v2 dưới 414px bị dư 24px). App shell không bao giờ cuộn ở cấp trang —
   mọi vùng cuộn đều nằm trong `main` với overflow riêng của nó. */
