/* ── DADALAB: SN Knowledge Base widget (ported from standalone POC v9) ──
 * Everything below is scoped under .dl-kb so it can live inside a normal
 * WP page — no bare tag selectors, no unscoped custom properties, no
 * global reset. The JS is unchanged from the POC: it only ever queries by
 * class name and id, never by tag, so none of that had to move.
 *
 * Typography is deliberately NOT the site's --dl-font (Manrope). This is
 * a working interface, not marketing copy about one — IBM Plex Mono/Sans
 * keeps it reading as its own product, distinct from the dl- chrome
 * around it. See knowledge-base page intro for where Manrope resumes.

   widget block itself. Native Fullscreen API on .dl-kb: the header's position:sticky
   keeps working because .dl-kb becomes the scrolling container (overflow-y:auto) rather
   than the page — so the header stays pinned while term cards scroll under it, same
   feel as the embedded view. Escape exits for free; no custom close control needed. */
