/* ================= DESIGN TOKENS =================
   Concept: the "graded exam paper" — pale sage notebook-paper
   background, ink-navy body copy, a red-pen accent used exactly
   the way a teacher's pen is used (corrections, circles, checks),
   and a muted gold "highlighter" for emphasis. Structure borrows
   from ruled paper (horizontal hairlines) and file-folder tabs
   (the nav). Numbers are used only where a real sequence exists
   (the D-day ticker, exam dates) — not as decoration.
