/*
  MyCollege Student Portal — single stylesheet of record.
  One font (IBM Plex Sans Arabic 400/500/700 — never other weights), one
  accent with a tint ramp, semantic colors distinct from the accent. Add
  styles through these tokens; do not start a new "alignment layer".

  PALETTE STATUS: DRAFT. Direction approved by the owner 2026-08-01 is
  "cool academic (indigo/blue)"; the concrete values below are placeholders
  until rendered samples are signed off. Change values only, never token names.
