Make every CoC classic-body column title bilingual — English (bold) over
the French translation (italic grey), matching Steelhead and the SO
report's stacked-header convention. Cert-info headers (Date of
Certification / Generated By / Work Order #) and line-item headers
(Process / Customer PO / Shipped / NC Qty / Customer Job No.) now show
both languages. First column carries Part Number / Line Item,
Description, and Serial Number, each translated. Bump reports 19.0.11.29.0.
Deployed + render-verified on entech (CoC-30065, 224KB).
