Krzysztof kuhy Rudnicki f7418969cf Freeze the motion, haptic and sound vocabularies, and ship them as tokens ... dopamine-ux prompt 01. The token layer froze colour, spacing, radius and type, but every animation in every app picked its own duration and curve out of the air -- so "200ms ease-in-out" and "180ms ease-out" both existed and neither was wrong, because nothing said what right was. unified-design-system/motion.md is the freeze: four durations, three curves, a haptic vocabulary mapped onto Flutter's HapticFeedback, and three sound cues, each with its one-line rationale. Shipped as AppDuration/AppCurve in Dart and --duration-*/--ease-* in CSS, so a consumer imports the scale instead of transcribing it. Three things worth stating, because they are the parts easy to get wrong: - Reduced motion collapses the *tokens themselves* (CSS @media, Flutter disableAnimations), so no consumer has to remember to branch. - Haptics and sound are NOT motion and are deliberately left alone by that preference. Suppressing animation is not a request to lose confirmation that a tap landed; the sound opt-out is a separate, user-facing setting. - Reward the recording, never the number recorded. The haptic fires on logging a meal, not on hitting a calorie target -- the latter rewards eating less rather than recording honestly, and corrupts the app's own data. gatelock stays untouched: Tkinter has no animation framework, so motion there is marked `n/a (tk)` rather than shipping a dead constant that reads as a supported feature. Tests assert the frozen values on both sides, and that the reduced-motion block collapses every non-zero step -- verified by mutation: deleting one collapse line fails the suite. flutter analyze / tsc / eslint clean, 68 Dart and 88 TS tests pass, palette_check and the 250-line cap still exit 0.
