/* ─────────────────────────────────────────────────────────
   Doc-site <details>/<summary> chevron — clean Lucide SVG
   ─────────────────────────────────────────────────────────
   The base classless.css draws a chevron with two rotated
   borders. That works in isolation but clashes whenever a
   doc page uses <details> in prose or in a demo, because
   the borders appear ALONGSIDE any custom chevron the page
   adds. Within the doc-site shell we replace the base
   chevron with a real Lucide chevron-down SVG so it always
   renders the same.

   Scope: only applies inside .dx-content (the doc-site
   article column) so it doesn't reach back into component
   demos that intentionally set their own.
