Specify micro-interactions and animation for developers

Help me write a motion and micro-interaction spec for developers. Interactions to specify: [LIST - e.g. "like button tap", "bottom sheet open/close", "toast appears and dismisses", "list item swipe to delete"] Purpose of each: [feedback / orientation / continuity / delight] Platform and tech: [iOS, Android, web CSS, React Native, Lottie] Existing motion tokens: [OUR DURATION AND EASING TOKENS - or "none"] Brand feel: [e.g. calm and quick, playful] For each interaction specify: - Trigger (user action or system event) and any conditions. - Elements involved and which properties change (opacity, transform, size, color), with start and end values. - Duration in ms, delay, and easing (named curve or cubic-bezier values), using my tokens where they fit. - Sequence or stagger for multiple elements. - Interruption: what happens if the user acts again mid-animation. - Reduced-motion alternative (respecting the OS setting), e.g. a fade instead of a slide. - Accessibility notes: nothing that flashes more than 3 times a second; state changes announced to screen readers. Guidance: keep most UI transitions roughly 100-300 ms, and avoid animating layout properties that hurt performance. If I have no tokens, propose a small set (e.g. fast, standard, slow; enter and exit easing). Return one spec table per interaction and a short tokens table.
