+## Deterministic SVG rendering
+
+The benchmark also includes a deterministic SVG rendering step:
+
+- Input: `artifacts/multi_family_admissibility_results.json`
+- Output: `artifacts/multi_family_admissibility_curves.svg`
+- Script: `scripts/render_multi_family_admissibility_svg.py`
+- npm command: `npm run generate:multi-family-svg`
+
+The SVG output is deterministic by design with fixed dimensions, fixed axes, fixed degradation level order, lexicographic family order, a hardcoded palette, no timestamps, no generated IDs, and no embedded JavaScript.
