Intent

• 用于动画性能审查与修复：当用户说动画卡顿、transition 发抖、scroll-linked motion 不顺、blur 太重，或要审查 CSS/JS 动画性能时使用。Combine with frontend-design or ui-ux-pro-max when 先做动效设计再做性能收口；Do not use for 纯视觉方向选择或非动效性能问题。

Default operating pattern

1. Clarify audience, surface, success metric, and implementation boundary.
2. Study relevant patterns, references, or constraints before proposing a direction.
3. Define structure, interaction, copy, and visual hierarchy with a reusable rationale.
4. Pressure-test accessibility, motion, maintainability, and platform fit.
5. Return a concise recommendation and the next implementation move.

Pack fit

• Included in: product-design
• Keep examples generic, privacy-safe, and portable across hosts.

Boundary

• Do not use for unrelated back-end or data-layer performance issues.
