Когда использовать
Drive a bounded 3D presentation from local section scroll progress.
Решения для реализации
- Compute and clamp section progress to 0..1.
- Interpolate authored rotations or camera positions continuously.
- Keep actions and text in semantic DOM.
- Provide a static composition for reduced motion.
Как проверить результат
- Scrolling upward reverses the timeline.
- The final section releases normally.
- The object cannot move behind the camera.
