   TG Access — design system
   Blue / white / silver. Light scheme, committed to deliberately.

   Written with CSS logical properties throughout (inline-start, margin-inline,
   border-inline) so the entire interface mirrors correctly for Arabic simply by
   setting dir="rtl" — no separate stylesheet, no overrides.
