Motion is part of the theme

Six settings describe how a product moves, and every duration, easing, lift and stagger follows from them.

Six settings: speed, bounce, travel, hover, stagger and decorative loops. Durations, easings, hover lift, button press and the CSS spring curve derive from them, and the defaults reproduce the current look exactly. See Motion settings.
Tailwind's scales follow: duration-75 to duration-1000, delay-* and the ease-* classes read the theme, and a new ease-spring is a real spring written as a CSS linear() easing. Dialogs, popovers, menus and accordions follow through tw-animate-css, with no edits to existing components.
Five ready-made feels, each its own registry theme: @ballmac/motion-native, -calm, -snappy, -playful and -still. Each of the twelve color themes carries a feel that suits it.
The theme builder has a Motion group (a personality picker and a slider per setting) and a motion lab with easing curves, hover and press, stagger, durations, JavaScript springs and loops; /themes?mo=playful opens a feel.
Motion presets 1.1.0 adds useMotion, useLoopsPaused and MotionProvider for the same numbers in JavaScript. See Use theme motion in your own code.
pnpm bump writes the version bump and changelog entry the version check asks for.

Reduced motion is part of the theme: a prefers-reduced-motion rule removes travel, lift, bounce and loops and keeps fades; the Still feel ships those values to every visitor.
Decorative loops (13 components) hold still when loops are turned off; spinners and thinking indicators keep running. Hover lift and button press follow the theme in Card, Button, Suggestion Chips, Workspace Card, three blocks and seven templates.
The Figma tokens export includes the motion settings as W3C duration and number tokens.
