- Drop chunk_bbox_page from Qdrant payload — viz endpoints never read it (page_number is the canonical PDF page field). - Bump upsert BATCH_SIZE 10 → 100 now that payloads no longer carry PNGs. - compute_chunk_bboxes_batch: move doc.close() into finally, replace unused stored_page_num with _. - purge_page_images.py: switch to anyio.run() per project convention, and wrap AsyncQdrantClient in try/finally so the aiohttp session is always closed (the class doesn't implement async-context-manager). - Decorate new bbox unit tests with @pytest.mark.unit so they run under the fast-feedback selector.

Replaces the legacy `highlight_chunks_batch`-+-base64 pipeline that inflated

Qdrant payloads with per-chunk PNG screenshots. The new path returns
