/* ============ Arabic page (lang="ar", dir="rtl") ============ */
/* Amiri carries the Arabic; Newsreader stays as Latin fallback for
   journal names and titles. Italic is a Latin convention: Arabic
   elements that were italic become upright and lean on the olive
   color instead. Letter-spacing breaks connected Arabic script,
   so it resets to 0 on Arabic text. */
