我还在学习主题和插件开发，所以有很多我不知道的事情，但我想尽可能为这个主题组件做出贡献。因此，我一直在查看 [Fix board button categories by nathan-nz · Pull Request #23 · discourse/discourse-kanban-theme · GitHub](https://github.com/discourse/discourse-kanban-theme/pull/23) 作为可能的起点。我有一个基本问题：在 [https://github.com/discourse/discourse-kanban-theme/blob/main/javascripts/discourse-kanban/lib/kanban-utilities.js](https://github.com/discourse/discourse-kanban-theme/blob/main/javascripts/discourse-kanban/lib/kanban-utilities.js) 和其他一些地方，有一个未初始化的变量名为 `settings`；它一定是由工具在某个地方设置的，我很想了解更多关于它的工作原理。这是 Ember 的一个功能，还是 Discourse 的主题驱动程序，或者其他什么？是否有关于类似变量的更多文档？
