ADDED Requirements

Requirement: Editorial motion tokens are centralized

The system SHALL define shared public motion tokens for an approximately 500 ms entrance, short interaction feedback, exponential ease-out, 90 ms stagger capped at 270 ms, 12 px vertical distance, and 24 px desktop / 16 px mobile lateral distance. Public motion CSS MUST consume these tokens instead of duplicating arbitrary values.

Scenario: Motion runtime uses shared values

• WHEN page openings, reveals, or interaction feedback are styled
• THEN duration, easing, stagger, and distance MUST be derived from centralized tokens
