module Rigor::ModuleGraph::Viewer

Interactive viewer that replaces the static-Mermaid HTML for view --output html. The output is a self-contained HTML file: vendored cytoscape.min.js is inlined alongside our ~100-line init script and the node / edge dataset, so the artefact opens in any browser without a network round trip. See docs/plan.md “2D interactive viewer” for the supply-chain rationale.
