Crate merman_render 

Headless layout + rendering for Mermaid diagrams.

This crate consumes merman-core’s semantic models and produces:

• a layout JSON (geometry + routes)
• Mermaid-like SVG output with DOM parity checks against upstream baselines

This low-level crate has no default diagram families. Select diagram-* features or all-diagrams explicitly; optional layout engines and math remain independent selectors. Family-owned typed layout APIs are conditional on those selections. Use family::supports_diagram_type to inspect this renderer’s local handler availability: another dependency may enable additional core parsers without enabling their renderers.
