"""策略参数寻优预设网格。

每个内置策略 1-2 个关键参数的合理取值列表，供：

1. Web UI 参数寻优页（``ParamGridPicker``）切换策略时自动填充——用户开箱即用，
   仍可编辑/取消勾选。
2. 「一键寻优所有策略」（``/backtest/optimize-all/run/async``）逐策略做网格
   寻优再全局排名。

约束：单策略笛卡尔积 ≤ 200（``ParamGridOptimizer.MAX_GRID_POINTS``）。行尾注释
标注该策略的网格点数。修改本文件即同步生效，无需重启策略注册表。

新增策略时：在 :data:`STRATEGY_PRESETS` 增加同名 key 即可；未登记的策略在
「一键寻优」中会被跳过并记录 warning。
