/**
 * bd-cursor — custom cursor system (native / label / badge / graphic / halo)
 * Version: 6.0.0
 * Model: ONE overlay element (.cursor-overlay) becomes the LABEL box, the BADGE
 *        circle, or the bare GRAPHIC by composing a shape class (.is-circle /
 *        .is-graphic / none = label box) with the root .bd-cursor-replacing flag
 *        (native hidden + halo off + larger "riding" size). Authored via
 *        data-cursor-label / -icon / -icon-end / -badge / -graphic, the
 *        data-cursor-replace boolean (hide native, the atom rides the pointer),
 *        and data-cursor-native (carve-out: restore the OS pointer inside a
 *        replace region). All glyphs are SVG <use> refs into sprites — no PNG.
 *
 * Portability: every design-system token is consumed through a --bd-cursor-*
 * component token with a literal fallback, so the file works on a page without
 * design-system.css. Re-theme by overriding the component tokens, never the
 * rules (same contract as bd-video.css).
 *
 * History: v5 renamed the surface to .cursor-overlay and split shape from riding
 *          state. v6 promotes the module into the design system: config-driven
 *          sprite paths in the JS, namespaced component tokens here.

     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 a router removes the element on
     navigation, the rule stops matching and the native cursor self-heals — no JS
