| 2 | + * SignatureMoment — 签名时刻（宪法第三条：全产品唯一一级时刻） |
| 3 | + * SignatureMoment — the one signature moment (constitution §3) |
| 4 | + * |
| 5 | + * @ai-context: 挂载点=掌握一个概念（费曼评估通过/卡片牢固）。三幕结构： |
| 6 | + * 第一幕·静默（1.5s 世界安静下来）→ 第二幕·事件（4.5s 星亮起+波纹+连线） |
| 7 | + * → 第三幕·余韵（2s 自动消散，痕迹已由 OrderRipples/星图永久保留）。 |
| 8 | + * 约束：Esc/点击可打断（觉察原则）；reduced-motion 降级为 3s 静帧卡； |
| 9 | + * 声音占一半（achievement_unlocked）；同屏仅一次（新事件重置计时）。 |
| 10 | + * |
| 11 | + * @ai-context: Three-act overlay driven by useWorldEvents.signatureSeq. |
| 12 | + * Interruptible (Esc/click), reduced-motion static fallback, sound included. |
