hebertzhu fixing-motion-performance
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-designorui-ux-pro-maxwhen 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
- Clarify audience, surface, success metric, and implementation boundary.
- Study relevant patterns, references, or constraints before proposing a direction.
- Define structure, interaction, copy, and visual hierarchy with a reusable rationale.
- Pressure-test accessibility, motion, maintainability, and platform fit.
- 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.
