Untitled string in Mermaid Config Schema

https://mermaid.js.org/schemas/config.schema.json#/$defs/UsecaseDiagramConfig/properties/colorScheme

用例图的颜色如何从活动主题中获取。role（默认）会给每种元素分配一种颜色，这些颜色取自 usecaseActorBkg / usecaseActorBorder、usecaseBkg / usecaseBorder 和 usecaseBoundaryBkg / usecaseBoundaryBorder 主题变量。颜色表示元素的“类型”，在插入、重新排序和重命名时保持不变——在中间添加一个用例不会重新着色后面的元素，因此差异对比、文档截图和视觉基线都保持稳定。而 rotate 则会给每个角色、用例和系统边界分配主题类别调色板（borderColorArray / bkgColorArray）中的独立槽，就像 ER 实体和类框的着色方式一样。角色和用例共享一个循环，而系统边界从零开始运行第二个循环，因此边界不会被迫与其中的元素匹配。在共享循环中，角色优先编号，用例紧随其后，按声明顺序排列——因此交错的 actor A、usecase U、actor B 的编号是 A、B、U，而不是 A, U, B. This buys per-instance variety at the cost of the stability role has: inserting an element shifts the colour of every later element of its own kind, and inserting an actor shifts the use cases too. Only the colour themes (redux-color, redux-dark-color) carry a palette, so on every other theme the two settings render identically.

classDef and style keep overriding both, whichever is set.
