/* =====================================================================
   3CS Class Hub - design tokens and base

   The look is a school notebook: graph paper underneath, clean white
   pages on top, ink for text, and the three colours from the Itz'at
   STEAM Academy logo doing distinct jobs:

     plum   (--brand)   the school, primary actions, the active section
     orange (--now)     time: "now", today, anything live or urgent-ish
     blue   (--info)    links, information, the calendar

   Shapes follow one rule: pages/cards 18px, controls 12px, chips and
   avatars fully round.
