Is your feature request related to a problem? Please describe.

Currently, we often encounter various discrepancies in the style of each page. While some can be fixed by AI, it's definitely better to do things that can be solved deterministically via deterministic tools.

The most recent find is about using - over * in bullet style lists: #1745, which was discovered by eslint, but it did not suggest easy fixes.

Describe the solution you'd like

We can try to resolve stylistic issues by using either eslint, remark, or both. And since the current eslint configuration seems to be lacking (cannot parse $...$ well, see #1744), we can temporarily switch to using remark instead. At least for markdown files — the eslint setup for the React components and other code files is rather fine.
