v0.1.13: 金碧山河（SVG/Canvas 素材 + 动效系统 + 舞美重装）

【素材生成（零外部资源）】
- scripts/gen-art.mjs 程序化产出 5 枚 SVG 资产：金碧山水全景（山脊/金乌/雁阵/水纹）、
  祥云纹带、回纹角饰、仙鹤、星辰层 → src/renderer/assets/gen/，npm run gen:art 可重跑

【Canvas 动效系统（单 RAF）】
- ui/fx-canvas.ts：灵雾粒子流(常驻随季色)/金砂喷发(spark)/刀光(blade)/涟漪(ripple)，
  单实例防重入、防膨胀 cap、GPU 友好、visibility 自停
- ui/fx.ts + core/fxqueue.ts：FxGate 统一发射闸——档位过滤(柔/标/全)、
  reduced-motion 降级、单帧批处理防竞态、deltas 纯函数(漂字差分)

【舞美】
- 金碧背景层 bg-scene（全页面，随季节 hue-rotate 色温渐变）
- 顶栏时辰司：季节印(春·熏风/夏·蝉鸣/秋·霜叶/冬·雪静)+年月进度环(SVG 弧段)+节气名
- 成员卡：闭关 aura 三点浮动 + 修为流光 shimmer
- 消息流：good 事件(突破/获宝/落槌)→金砂喷发，战事→刀光扫过战报
- Boot 卷轴展开过渡；drift 漂字层(独立节点队列不覆盖，8 条裁剪)
- 设置页动效三档（柔和/标准/全开）

【竞态规避】
- RAF 单循环 guard、particles cap 裁剪、FxGate draining 互斥、漂字节点附加不覆盖、
  visibility 自动降级、advance in-flight 闸沿用

【测试】937→967（timesense 矩阵 15 + FxGate 竞态/档位/deltas 15）
全量 35 套件通过；金钟罩零漂移（纯 UI/素材层）；typecheck/build 通过
