How do you design well for Arabic and Somali (RTL + LTR) at once?

Many of us build for audiences reading Somali, English, and Arabic — and Arabic flows right-to-left. How do you keep layouts clean across all three?

What's worked for me:

• Design with logical properties in mind (start/end, not left/right) so layouts mirror cleanly.
• Don't just flip — icons with direction (arrows, back buttons) need to mirror; logos usually don't.
• Test real Arabic text early; line height and font choice matter a lot.

How do you approach bilingual or trilingual layouts? Any fonts that handle Latin + Arabic gracefully?
