/* Yusr — design notes
   Direction: a mihrab arch is the one memorable shape; everything else stays quiet.
   Palette: mist (page), paper (surfaces), lapis night ink, lapis (action), saffron (light accent).
   Type: system serif (headings, Arabic) + system sans (body). No external fonts: nothing loads from third parties. */
