/* Academic Attendance — design system (V13.3)
   One stylesheet for the launcher, department, teacher, admin and student pages.
   Palette from the college identity: deep ink green, Yarmouk green, restrained gold.
   Gold marks only what is live right now (an open attendance window).
   Type: Noto Kufi Arabic for titles, labels, buttons and figures (the formal,
   institutional voice); Noto Naskh Arabic for running text, names and fields
   (the script of official letters). Both bundled, OFL. */
