One pattern per page, each built to settle a single argument. These are
the pieces the template prototypes on the
Motion Lab homepage are assembled from. Durations,
easings, travel and stagger all come from src/motion.css.
Every demo carries a review toolbar. Drop Speed to 0.2x to watch an easing curve resolve, toggle Reduced to review the accessibility fallback as a real design state, and press H to hide the toolbar for screen recordings.
