What “supports Arabic” means here
It means three separate surfaces, not one. The dashboard you work in is Arabic. This marketing site has an Arabic twin of every page, cross-linked with hreflang so a search engine serves the right one. And the landing pages your QR codes actually open — menus, contact cards, link-in-bio pages, forms — render in Arabic for the people scanning them.
The third one is the one that usually gets missed, and it is the one your customers see.
Native RTL, not a flipped stylesheet
Layout uses logical direction properties throughout, so spacing, alignment and icon direction resolve correctly in both directions instead of being mirrored after the fact. Mixed content behaves: a Latin brand name, a URL or a number inside an Arabic sentence keeps its own direction rather than reversing.
Arabic has six plural categories rather than two, and counts across the product use them, so a number is never followed by a noun in the wrong form.
The scope, stated honestly
Arabic and English are the two supported languages, deliberately. There is no half-finished third locale sitting behind a flag, and the Arabic is written rather than machine-translated.
