   Typography - IBM Plex, self-hosted (no external requests, CSP-safe)

   IBM Plex is IBM's corporate typeface: a neutral, engineered grotesque built
   for technical communication. IBM Plex Sans Arabic is the matching Persian /
   Arabic cut by the same foundry, so both languages share one type system -
   identical weights, metrics and tone.

   Latin ranges deliberately exclude U+200C-200D (ZWNJ / ZWJ): those belong to
   the Arabic face, because Persian word joining depends on them.
