Runs mermaid 12.2 from node_modules (no CDN) in a fresh incognito Chrome context with all network requests blocked, initialised with securityLevel strict (labels sanitised, no click callbacks, no HTML labels) and deterministic ids; directives cannot lift the protected security keys. Syntax errors return the parser message. PNG is rasterised by Chrome from the SVG.
