Foundations

Motion

Three durations and two easings. Every animation respects the user's reduce-motion preference. The triage swipe uses the spring; everything else uses ease-out.

Durations

120ms

Micro-interactions — toggles, hover reveal

200ms

Default — most transitions, standard easing

320ms

Larger moves — sheets, tab changes

Easings

cubic-bezier(0.2, 0.8, 0.2, 1)

Standard — everything except the triage spring

cubic-bezier(0.34, 1.56, 0.64, 1)

Triage-card physics

Shadow (popovers only)

shadow.popover

Menus and sheets only. The rest of the system is flat.
