- repository: Named rule groups for reuse via
#name - match: Single-line regex pattern
- begin/end: Multi-line patterns with nested content

Key Patterns
- Use
capturesto assign scopes to regex groups:"captures": { "1": { "name": "..." } } - Use
contentNamefor scope of content between begin/end - Escape backslashes in JSON:
\\bfor word boundary - Order matters: first matching pattern wins
