Motion Word - name the UI motion you mean, then build it right

Describe a web animation in your own words and get its exact name from a 91-term motion glossary where every term plays live, with close alternates and a prompt phrase. Then turn the term into a build spec - should it animate at all, the purpose, the tool, the properties, the curve and duration from fixed tables or a spring, the exit and the reduced-motion variant - with copy-ready CSS, a page check against the tables and a slow-motion preview. Built on Emil Kowalski's @emilkowalski/animation-vocabulary and @emilkowalski/animate skills (MIT).
