/* Closed drawers must leave the tab order.
 *
 * Every drawer on this site is hidden by transform alone, which moves it out of
 * sight but leaves it focusable and in the accessibility tree. On all 180 pages
 * a keyboard user could tab off the header and land inside an invisible cart —
 * quantity steppers, then the Stripe and PayPal checkout buttons — with no
 * visual indication of where focus had gone.
 *
 * visibility:hidden removes an element from both the tab order and the a11y
 * tree. Delaying its transition until the slide-out has finished (and applying
 * it instantly on open) keeps the animation exactly as it was. The `inert`
 * attribute is toggled in JS as well, for browsers that predate this behaviour
 * and to cover programmatic focus() calls, which visibility does not block. */
