Missing brand attribute

Meta requires a brand on every product. Without it the catalog item is disapproved and won't appear in Facebook or Instagram Shops.

Feed exports without a brand column, or relies on inheritance from parent products that didn't have brand set.

1. Add brand to every product. Use the manufacturer's brand name.
2. For private-label, use your private-label brand.
3. Don't use 'Generic' or 'No Brand' — Meta rejects placeholders.

• Inheriting brand only on parents, missing on variants
