/* ==========================================================================
   AI SEO NEGARNOVIN — frontend.css  (v3.4.0)
   FAQ accordion + TL;DR + AI link glassmorphism button + dark mode.

   v3.4.0 CHANGES:
   - FAQ: hide default <summary> marker (::-webkit-details-marker)
   - FAQ: smooth max-height transition for open/close
   - FAQ: first item open by default (via JS)
   - AI button: stronger !important rules (survives theme conflicts)
   - AI button: better dark mode (auto + manual + force)
   - AI button: z-index 2147483000 (max, above everything)
