Show HN: Mmdr – 1000x faster Mermaid rendering in pure Rust (no browser)

I was building a Rust-based agentic coding TUI and needed to render Mermaid diagrams. Noticed the official mermaid-cli spawns a full browser instance (Puppeteer/Chrome) just to render diagrams. Decided to fix this. mmdr is a native Rust renderer. No browser, no Node.js. mermaid-cli: ~3000ms per diagram mmdr: ~3ms per diagram Supports 13 diagram types: flowchart, sequence, class, state, ER, pie, gantt, timeline, journey, mindmap, git graph, XY chart, and quadrant.
