# Micro-interactions Use when adding motion or feedback — fast, purposeful, interruptible, and reduced-motion aware. ## Checklist - Every action needs feedback inside 100ms, even if the result is slower. - Keep transitions in the 150–250ms range; longer reads as sluggish. - Ease out for entrances, ease in for exits. - Animate transform and opacity only — anything else costs a layout pass. - Motion should explain a change of state, never decorate an idle screen. - Honour prefers-reduced-motion with a cross-fade instead of movement.
