/**
 * Keep a marquee clone's content pointer-CLICKABLE while taking it out of the
 * accessibility tree and the keyboard tab order. Shared by every endless-loop
 * surface that renders a second track copy (<CardsStrip> managed cells,
 * <MarqueeWall> clone copies).
 *
 * `inert` (the previous approach) does all three at once: a11y-hidden,
 * un-focusable AND un-clickable. That third effect was the "news marquee stops
 * being clickable after you scroll it for a while" bug — the 2-copy endless
 * loop ALWAYS paints clone cards inside the viewport near the copy seam, so a
 * user who manually scrolls and parks there is looking at real-looking cards
 * that silently swallow every click. Clones must therefore stay clickable (a
 * click on ANY visible card must open its link — mouse, ⌘-click, middle-click
 * and context-menu all handled natively by the clone's own anchor).
 *
 * The a11y contract is still met without `inert`: the caller keeps
 * `aria-hidden` on the clone wrapper (out of the a11y tree) and this hook
 * forces every focusable descendant to `tabindex="-1"` (out of the tab order →
 * no duplicate tab stops, no aria-hidden-focus violation). Re-applied on
 * subtree mutation. This is the standard loop-clone treatment used by
 * Swiper/Splide.
