What to build

Turn brand pages into concise shopping surfaces that establish only verifiable brand context, expose the relevant product categories, and lead immediately into products. Avoid generic brand storytelling and keep the same catalogue interactions customers learn elsewhere.

Acceptance criteria

• The header shows the brand name, accurate available-product count, and concise verified context.
• Relevant categories within the brand are directly selectable.
• Products and refinement controls precede secondary descriptive content on mobile.
• The page uses the shared catalogue, filter, sorting, card, and pagination behavior.
• Missing optional brand content degrades to a clean product-first page.
