Companies can upload a logo and a stamp/seal (Admin → Companies → Edit →
Branding); both render on exported PDF and XLSX purchase orders. A fixed
brand-colour bar (#92D050, matching the sample PO) runs along the bottom of
every export.
- Company.logoKey / stampKey + migration
- buildCompanyAssetKey() deterministic storage keys (overwrite-in-place)
- uploadCompanyAsset / removeCompanyAsset server actions (≤4MB PNG/JPG/WebP,
manage_vessels_accounts gated)
- CompanyBrandingUploader in the company edit dialog with live previews
- Export route embeds logo (top-left), stamp (signatory block) and brand bar
in both ExcelJS and print-HTML paths
- Unit test (storage keys) + integration test (branding actions)
