70-78: Good call on scss fence for nested @media example.

No content change; improves highlighting of nested rule.

Please confirm the docs site’s highlighter (e.g., Shiki/Prism) treats ```scss inside Markdown as expected and doesn’t affect copy-to-clipboard formatting.

98-108: Using scss fence here correctly highlights nested &:hover.

Reads better; no semantic changes.

If you add the clarification note suggested above, this block will be covered by that context as well.
