**nitpick:** The Arabic translation uses "كالملف الأصلي" ("like the original file") instead of clearly expressing "as the original file/path"; the warning does not accurately tell users that saving over the original file is prohibited.

**Suggested fix:** Use wording such as `لا يمكن الحفظ باسم الملف الأصلي في وضع المعاينة. يرجى اختيار مسار مختلف.`
