/* Masari
   K & A Study Hub's look, as asked: the warm cream page, navy ink, coral
   buttons with a pressed edge, round friendly type, generous corners. Phone
   first; the same pages widen for tablets and computers. Written with
   logical properties (inline-start/end) so Arabic, right to left, needs no
   separate stylesheet. No glows, no emoji. */
