What problem does it solve? Static interfaces often lack feedback, feel abrupt during state changes, and miss opportunities to guide users, making them harder to understand and less engaging to use. ## Core Features & Use Cases - Animation Opportunity Assessment: Identifies missing feedback, jarring transitions, and unclear relationships in a feature before writing any motion code. - Systematic Motion Implementation: Covers entrance animations, micro-interactions, state transitions, navigation effects, and delight moments with concrete timing and easing guidance. - Accessibility and Performance Guardrails: Enforces prefers-reduced-motion support, GPU-accelerated transform/opacity animations, and 60fps performance targets. - Use Case: After shipping a checkout form, use this Skill to add button press feedback, validation shake on errors, smooth accordion transitions, and a success celebration while keeping reduced-motion users supported. ## Quick Start Review the checkout flow and add purposeful animations and micro-interactions that provide feedback and smooth state transitions.
