Example: Submenu navigation with clear direction and continuity

History enters from the right, aligned with its chevron. The parent menu shifts and dims to preserve context. Back reverses the path, so the motion feels navigational — not decorative.

Ease: Emphasized (slide); Standard (fade). Timing: slide 185 ms in; 130 ms sub out, 150 ms parent out; fade ~90–110 ms, quicker than slide.
