   Design tokens: color, type, spacing, radius, shadow, motion.
   Brand palette supplied by the school:
     #055BA6 (dark blue)  #0568A6 (blue)        #18A2D9 (light blue)
     #F28C0F (orange)     #0D0D0D (black)
   Audience: older, non-technical staff on desktop, weak connectivity.
   Priority: legibility and unambiguous state over decoration (§11, §72).
