   One stylesheet, two scripts (Latin and Persian), no framework.

   Everything is written with logical properties so the Persian pages are the
   same layout mirrored, not a second layout. Type is the one place the two
   languages deliberately diverge: English gets an editorial serif for display
   and a grotesk for text; Persian gets Vazirmatn for both, because a Latin
   serif has no Arabic-script glyphs and a mixed display face reads as a
   mistake to a Persian reader.
