Build-an-X workflow for verifying RTL (right-to-left) layouts - runs the test suite under Arabic / Hebrew / Persian / Urdu locales, asserts the `dir="rtl"` attribute is set, verifies layout mirrors correctly (text alignment, icon positions, scrollbar location), uses logical CSS properties (`start`/`end` over `left`/`right`) per W3C guidance, captures per-locale screenshots for visual review. Use when the app supports RTL languages.
