Find the leading theme, hold it while trend is healthy, and raise cash when risk breaks. Discipline, not prediction.寻找主导主题，趋势健康时持有，风险破坏时提高现金。这是纪律，不是预测。
Read解读: AI Compute & Optics leads the themes (durability firm); leadership is narrowing (6/22 themes in uptrend); suggested cash 0%.AI算力与光模块 领跑主题（持续性中）；领跑面 收窄（6/22 个主题处于上行趋势）；建议现金 0%。

Equal-weight by design. The rank tells where to look; trend decides whether to hold. Crowding is shown as caution only; it is not a weight cut yet.刻意等权。排名说明看哪里，趋势决定是否持有。拥挤度仅作提示；尚不削减权重。
