/**
 * bd-cursor — Tooltip-style cursor label
 * Version: 4.0.0
 * Updated: April 29, 2026
 * Changes: Pivoted from icon-replacement to additive tooltip-style label.
 *          Native cursor stays visible always. Content driven by HTML
 *          (data-cursor-label, data-cursor-icon, data-cursor-icon-end).

     once the cursor is confirmed live (desktop, not reduced-motion, DOM
     present), so no-JS / reduced-motion / init-failure never hide the cursor
     with nothing to replace it. The descendant rule is required because
     children set their own cursor (e.g. cursor:pointer on links). When Barba
     removes the element on navigation, the rule stops matching and the native
