Every UI library treats animation as decoration. FLUX UI treats it as a language. 40 composable motion primitives powered by a unified physics engine with 7 named spring presets. Built on React 19, Tailwind CSS v4, and Framer Motion. Three-tier accessibility baked in. Zero visual lock-in primitives add motion behavior only, you bring your own design. Ships with gesture composition, scroll-linked animations, ambient backgrounds, and first-class AI patterns that no other library offers.
