GSAP is the industry standard for performant web animations, and this skill brings that power to JARVIS HUD interfaces. It covers the essentials: GPU-accelerated panel transitions, status indicator sequences, and data visualization animations. The implementation is solid on fundamentals like respecting prefers-reduced-motion, cleaning up timelines on unmount, and using transforms instead of layout properties. The TDD approach is thorough, with tests for animation lifecycle and memory leaks. If you're building anything with smooth UI transitions or need complex timeline sequences, this gives you the patterns to do it right without thrashing the layout engine.
