/* ==========================================================
   auimlab Articles Page v4 — web-designer skill 集成 (2026-08-09)
   灵感: Linear 暗黑精度 + web-designer 动画 playbook + auimlab 紫青色品牌
   本版变更 (v3 → v4):
   - 集成 web-designer skill (MickeyAlton33/web-designer-plugin, 82 stars)
     5 个 supporting docs: animation-playbook / anti-patterns /
     color-and-typography / design-patterns / interactive-features
   - 全局动画系统: ease curves + reveal / stagger / word-reveal classes
   - 文章卡 hover 升级: directional underline + card lift + image zoom (动态感)
   - Hero h1 word-reveal: 字逐个 fadeUp, 50ms stagger
   - 文章列表 stagger reveal: IntersectionObserver + 80ms stagger
   - 搜索按钮 text-swap: "搜索" ↔ "→"
   - ⌘K hint: 搜索框右侧命令面板提示
   - font-feature-settings: 'cv01', 'ss03' (几何 Inter, Linear 精髓)

   v3 → v4 实测对比:
   - hero h: 295 (无变化)
   - 文章卡 hover 时长: 150ms → 400ms (动态感 +167%)
   - 文章卡入场: 无 → stagger fade-up (新)
   - 文章卡 hover 效果: opacity 0.8 → translateY -4px + shadow (新)
   - 标题入场: 无 → word-by-word (新)
   - 搜索按钮: 无变化 → text-swap (新)
