--- 75. exam_response_areas.meta — rich recognition payload from the extraction service (P2)
---==========================================================================================
--- The extraction service (docling-exam-spike analyse contract) returns richer per-region detail than
--- the thin first-pass could: per-option OMR box geometry + fill (boxes[]), select_n ("tick 2 of 5"),
--- n_options, the expected unit/quantity for single-line answers, and the data_table an MC question reads.
--- These have no dedicated columns; keep them in a jsonb sidecar so the canvas can render tick boxes /
--- units / MC option counts without a column per attribute. Nullable, defaults to {}.
