Define
English and Arabic are designed as two faces of one piece, not a translation dumped under the original.
Mechanism
Parallel rhetoric. Each language gets a real headline, a real hierarchy, a real close. Direction, type, and claim are planned together.
Verdict
The audience is mixed, or the same person switches languages by context: work and home, feed and pack.
Don't
One language is a legal afterthought. A bad Arabic face tells the Arabic reader exactly what we think of them.
