Can affiliate links be added later?
Yes. Product cards are structured so buy buttons and affiliate links can be added without changing the site layout.
Why the layout is prepared early
A product-led site should reserve clear product card areas before affiliate links are ready. That prevents later redesign work and keeps the user path from article to product stable.
What changes later
When real products are selected, each card can receive a product image, price note, merchant label, and buy button. The content structure can stay the same.
