/**
 * Breadcrumb — where this page sits, and how to get back up.
 *
 * WHY AN ORDERED LIST INSIDE A NAMED LANDMARK
 *
 * The trail is a sequence, and `ol` is what says so: a screen reader announces
 * "list, 4 items" and the position within it, which is the entire content of a
 * breadcrumb. A row of `div`s with slashes conveys none of that, and the
 * slashes themselves get read out as punctuation.
 *
 * The separator here is drawn by CSS `::before` on each item after the first,
 * so it is decoration that never enters the accessibility tree. Putting a "/"
 * in the markup is the usual version of this component and the usual defect.
 *
 * THE LAST CRUMB IS NOT A LINK
 *
 * `isCurrent` renders text with `aria-current="page"`. A link to the page you
 * are already on is a dead control: it announces as a link, invites a click,
 * and does nothing. This is the most common breadcrumb bug and the reason the
 * prop exists rather than being inferred from position — a trail whose last
 * crumb IS a link to somewhere else is legitimate, and inferring would break it.
