/* AUDIKUNG paper reading system — shared standard (Audi 2026-10-11).
   Navy page = navigation, hero, headings and interactive charts. Paper = reading surfaces only.
   Rules: one paper box per section · no box inside a box (inner structure = rows, hairlines, type) ·
   5 tokens + 4 semantic tints · 3-step type scale, body ≥ 16px, measure ≤ 68ch · every panel uses --ak-pad.
