// 动效时长合规审计(Task #16 专项盘点)
|
||
//
|
||
// 权威约束:CONTEXT.md L49-61「动效设计四原则」(✅ 2026-06-29 确认)
|
||
// 原则2 Fast :入场 200-300ms,hover 150ms,反馈 100ms
|
||
// 原则4 Layered:子元素入场 stagger 30-60ms,Section 间 stagger 100-150ms
|
||
// 禁止事项 :禁止超过 700ms 的入场动效(硬上限)
|
||
// 注:700ms 是「禁止超过」的硬上限,不是目标值。目标值是 200-300ms。
|
||
//
|
||
// 扫描四类写法:
|
||
// 1. framer-motion transition: { duration: <秒> }
|
||
// 2. Tailwind CSS 类 duration-<毫秒>
|
||
// 3. StaggerReveal staggerDelay / delayChildren
|
||
// 4. 显式 delay(含 i * N 的递增延迟)
|
||
// 排除:node_modules / dist / coverage / e2e / _archive / *.test.* / *.spec.*
