/* ARRFLIX 2026-05-09 — incident fixes (see docs/26-incident-2026-05-09-...).
   1. Cineplex theme hardcodes German "Abspielen" via ::after on .play_arrow.
      Override with English. The German text was in CSS, not Jellyfin locale —
      so all Traefik Accept-Language rewrites + force-english-all-users.sh
      chases never fixed it.
   2. The BLACK-PASS block paints #000 !important on .layout-desktop,
      .pageContainer, .padded-bottom-page etc — these wrap the backdrop layer
      (z-index:-1) and occlude it. Use :has() to scope only when an
      .itemDetailPage descendant exists, so backdrop renders only on detail
      pages. */
