Module mermaid 

Mermaid code block extraction, rendering via mmdc, and content-hash caching.

Renders mermaid diagrams as halfblock images when:

1. mmdc is installed
2. Terminal supports inline images (Ghostty, iTerm2, Kitty)
3. NOT inside a multiplexer (tmux) which strips graphics escape sequences

Falls back to styled source code otherwise.
