remark-lint-blockquote-indentation

A remark-lint rule that warns when block quotes are indented too much or too little, checking the `>` marker and the spaces before content. The `remark-lint` ecosystem provides over 100 rules for linting Markdown. Current stable version 4.0.1 (ESM-only, requires Node.js 16+). Part of the unified/remark ecosystem, maintained by the remark team. Key differentiator: deeply integrated with remark-lint presets like `remark-preset-lint-consistent` and `remark-preset-lint-markdown-style-guide`.
