Code & diagrams

Syntax-highlighted code blocks and sanitized Mermaid diagram rendering, without a separate diagramming tool.

Code blocks get syntax highlighting and support grouped, tabbed code examples for showing the same snippet in multiple languages.
Mermaid diagrams render directly from a fenced code block — no separate diagram editor or exported image to keep in sync.
Rendered Mermaid output is sanitized before it's inserted into the page, so a diagram can't become a script-injection vector.
Code fence metadata (like a filename or highlighted line range) is supported, so a snippet can point a reader at exactly the line that matters.
