06 · Motion

Motion

Interaction rules — press feedback, gated hovers, custom easing, and reduced-motion support.

Press feedback

Buttons scale to 0.97 on press. Linked artifact cards scale to 0.99. Transform only, 150ms, var(--ease-out).

Fine-pointer hover

Decorative hovers (nav color, card glow) use the pointer-fine: variant — gated to @media (hover: hover) and (pointer: fine). Touch taps do not leave sticky hover states.

Easing tokens

Click a curve to pause or resume the loop. The dot moves at linear time while following the easing output.

Reduced motion

When prefers-reduced-motion: reduce is set, press transforms and decorative hover glows are disabled. Color and opacity transitions remain for comprehension. Tab indicator motion is disabled.
