(`AGENTS.md`, `GEMINI.md`) instead of a per-file rule directory. With
it, each harness wraps the body in its own scoping syntax.

Multiple globs are supported via comma-separation:

```yaml
applyTo: "**/src/**,**/api/**,**/services/**"
```

Targets that use YAML lists (claude, cursor, windsurf) expand the
comma-separated value into a proper list automatically. Brace
alternations like `**/*.{css,scss}` are treated as a single glob and
are not split.
