+### Mermaid Diagrams
+
+Fenced code blocks tagged ` ```mermaid ` are rendered as ASCII art instead of
+plain text when the diagram is a simple `graph`/`flowchart`:
+
+```mermaid
+graph TD
+    A[Start] --> B{Is it working?}
+    B -->|Yes| C[Great success]
+    B -->|No| D[Debug it]
+```
+
+This only understands a small subset of mermaid flowchart syntax (nodes,
+shapes, and edges with optional labels). Other diagram types (sequence,
+class, gantt, ...) and advanced flowchart syntax fall back to a regular,
+syntax-highlighted code block.
