     out of scope for this pass per the multilingual brief's own stop
     condition; a same-quality recommendation (Google Fonts "IBM Plex Sans
     Arabic" alongside a "Noto Kufi Arabic" display cut) is flagged in the
     final report instead. Until then, this is a safe, OS-native fallback
     stack — every platform's own default UI font already renders Arabic
