Make explicit that ALL formatting/HTML is owned by recipe-report.py render() and the model's only artifact is the spec JSON — never hand-write/edit HTML. Matters now that glm-5.2 drives the report. Also fix stale 'default opus' refs (report now defaults to opencode-go/glm-5.2, overridable via REPORT_BACKEND/REPORT_MODEL). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
