Adds the numbered 'III' chapter heading above the existing Worker
Breakdown card (the widest table in the report). Promotes the table
to .report-numeric (tabular-nums) for perfect column alignment
across dynamic adjustment columns — Inter's tabular-nums variant
keeps the rand amounts pixel-aligned.
No data or structural changes to the breakdown itself.
