 * Drives horizontal scroll of the actions toolbar's inner content via a
 * transform translate, exposing arrow visibility flags and press-and-hold
 * scroll controls.
 *
 * The viewport caps at the editor's safe area on desktop; when the content
 * (icons, options, action buttons) is wider, the user scrolls by pressing
 * and holding the arrow buttons rendered on the viewport edges. The
 * underlying transform is applied without a CSS transition so selection
 * changes don't animate back to zero. Mobile is unaffected — the options
 * strip keeps its own native horizontal overflow there.
