   v3.4.1 drawer (replaces A1 fold — user 没感知 rotateY fold, 抽屉感更强)
     · Trigger A: section enter → whole stage slides in from right (60% → 0)
     · Trigger B: tab switch → outgoing slides left (-60%), incoming slides in from right (+60%)
   A2 · red 章戳 indicator slides between tabs + pulse + red-glow halo on land
   A4 · 案卷夹合上打开 — twin flaps cinch over stage between tabs (缩短到 0.28s)
   B3 · section-title red-line wipe (scroll-trigger scaleX 0→1)
   All transform/opacity — GPU composited. Reduced-motion fallback at end.
