   RTL — OVERRIDES
   These selectors only fire when dir="rtl" / lang="ar" is on <html>.

   Helvetica Neue / Segoe UI / Arial stack as English.

  FIX: Duplicate logo in BOTH languages.
  .hero__logo lives inside #hero (not the header). On desktop the fixed
  header-logo is simultaneously visible at the top of every viewport, so
  both logos are seen at once. Hiding .hero__logo unconditionally removes
  the duplicate in English and Arabic — the header-logo handles branding.
