### 🆕 Report Engine Highlights
-**IR → HTML/PDF rendering**: New `ReportEngine/renderers/html_renderer.py` and `pdf_renderer.py` ship with a Source Han Serif subset plus offline MathJax/Chart.js/html2canvas; `report_engine_only.py` lets you render reports from the CLI without the web UI.
-**PDF export APIs**: Added `/api/report/export/pdf/<task_id>` and `/api/report/export/pdf-from-ir`, performing Pango dependency checks and returning vector PDFs that mirror the HTML preview.
-**Chart.js safety guardrails**: `utils/chart_validator.py` with optional LLM repair ensures widget payloads are valid, avoiding crashes or XSS from malformed chart configs.
-**Multi-source log console**: Frontend console now uses a double-buffered virtual list with SSE replay; backend exposes `/api/report/log` and `/api/report/log/clear` for quick inspect/reset.
