Individual skill

motion-foundations

Motion tokens, spring presets, performance rules, device adaptation, accessibility enforcement, and SSR safety for React / Next.js using motion/react. Foundation layer — all other motion skills depend on this. Use when setting up motion tokens, spring presets, reduced-motion handling, or SSR-safe animation in React or Next.js.

# Motion Foundations

The base layer of the motion system. Defines every value, constraint, and
rule that downstream skills (`motion-patterns`, `motion-advanced`) inherit.
Load this skill before any animation work begins.

## When to Activate

- Starting any animated component from scratch
- Setting up tokens, spring presets, or easing values
- Implementing `prefers-reduced-motion` support
- Debugging hydration mismatches from animation initial states
- Evaluating whether an animation should exist at all
