**BREAKING CHANGE:**
The previous `<!-- @include: ./path/to/file -->` syntax silently ignored errors when files did not exist. This behavior was originally intended as an escape hatch while documenting includes, but better solutions now exist using Shiki transformers.
For most users, no code changes are required. If you now see errors, it means your includes are broken and were previously not being reported.
Users who intentionally reference non-existent files or want to document includes without resolving them can configure `markdown.codeTransformers` with a `postprocess` hook. See `docs/.vitepress/config.ts` in this repo for an example.

- When clicking a tab in a named group, all groups with same name sync
- Add E2E test for synchronization behavior
- Update documentation to explain sync purpose and usage
- Add second test fixture for testing sync between groups
- Add optional group-name parameter to code-group containers
- Validates group names (alphanumeric, hyphens, underscores only)
- Adds data-group-name attribute to generated HTML
- Includes E2E tests for validation and functionality
- Updates documentation with usage examples and guidelines
BREAKING CHANGE: `includeFiles` option in `postcssIsolateStyles` now defaults to `[/vp-doc\.css/, /base\.css/]` You can remove explicit `includeFiles` if you were using it just to run it on `vp-doc.css`. To revert back to older behavior pass `includeFiles: [/base\.css/]`. The underlying implementation is changed and `transform` and `exclude` options are no longer supported. Use `postcss-prefix-selector` directly if you've advanced use cases.
