Prompt + Trace

1. Prompt bundle: pages_calendar_v1
2. Scene key: month_calendar
3. Task key: calendar_weekday_occurrence_query
4. Prompt query key: weekday_occurrence_date
5. Trace records the month/year, displayed week start, weekday/ordinal operands, answer date, and date-cell bboxes.
6. Generation is deterministic from instance_seed; answers and annotation come from the finalized calendar metadata.
7. Displayed week start is a scene/rendering axis (monday|sunday) and is not a public query_id.
