/* ============================================================
   AsiaAI.FYI — Videos
   ------------------------------------------------------------
   Additions only, same approach as guides.css. Everything below is
   built from the --asiaai-* tokens already defined in style.css — no
   new colors, no new fonts, no new radii. The tab control deliberately
   borrows the geometry of .asiaai-guide-filters__chip so the Videos
   page reads as a sibling of the Guides hub rather than a new idea.

 * left edge — which is exactly what happened here.
 *
 * display must be scoped to [open]: an unscoped author display value
 * beats the UA's dialog:not([open]) { display: none } and leaves the
 * closed dialog sitting on the page.
