- ## Operating Contract

+ ## Use This Skill

- 1. Inspect the existing project before changing code.

- 2. Identify the motion stack, scroll behavior, component lifecycle, reduced-motion handling, and available verification commands.

- 3. Keep motion purposeful: clarify sequence, focus, depth, tactility, or product understanding.

- 4. Follow existing project conventions unless a change clearly improves the result.

- 5. Run available checks and visually inspect responsive/reduced-motion output when the change affects UI.
