## What it does
Flags bulleted lists whose items use a mix of marker characters (`-`, `*`, `+`) within the same
list. Ordered lists are not affected.
## Why
CommonMark says any of `-`, `*`, `+` is a valid bullet marker; switching markers between items
either (a) reads as a typo, or (b) actually starts a _new_ list under CommonMark's rules, which
produces a visible gap in the rendered output that the author rarely intended. Either way the
fix is to pick one marker per list and stick to it.
The formatter normalises markers across the whole document; this rule fires when the source as
written would render two adjacent lists when one was meant.
## Example (bad)
```markdown
- first
* second
- third
```
## Example (good)
```markdown
- first
- second
- third
```
