Follow the instructions in ./workflow.md.
./steps/step-01-route.md. Pick one diagram type from the routing table (references/activation-routing.xml) based on user intent (teach, brainstorm, UX flow, funnel, technical explainer, medical, creative, or page mockup)../steps/step-02-draw.md. Design the diagram using the shared shape grammar (references/fundamental-shapes.md), then write the .excalidraw JSON file with a non-empty elements array to /tmp/hand-drawn-diagrams/<slug>/../steps/step-03-validate.md. Run scripts/validate_excalidraw.py, then scripts/open_diagram.py to generate a hosted edit URL and open it in the browser.

See INSTALL.md for setup. Without it, rendering falls back to Playwright.
