/* ============================================================
   CBQ Interstitial Ad — post-submit overlay (v4.3.0)
   Shown between Submit click and Result display. Free users only.
   ============================================================ */

/* v4.12.433 — CRITICAL FIX. Without this rule, the `display: flex`
   below overrides the browser's default `[hidden] { display: none }`
   user-agent stylesheet, making the overlay PERMANENTLY VISIBLE on
   every page load — even though the HTML has `<div ... hidden>`.
   The JS controller's MutationObserver never fired because `hidden`
   never had a chance to mutate (it was visually ignored), so the
   countdown logic never ran → ad stuck at "5" → user trapped. */
