Epic 9: Shop & checkout (Amazon affiliate)

[Tar-ive]

Reshaped from docs/user-stories.md. Legend: ✅ Live · 🟡 Partial · ⚪ Planned.

Personas: Giver

• 9.1 Browse the shop ✅ — As a Giver, I want a hand-picked shop, so that I have a trusted set of buyable gifts.
  • /feed/shop tiles from Amazon ASINs with a visible affiliate disclosure.
• 9.2 Compliant outbound buy links ✅ — As a Giver, I want safe Amazon buy links.
  • rel="sponsored nofollow" + Associates tag; ASIN-only (no scraped prices/images), per the Operating Agreement.
• 9.3 International shoppers earn correctly 🟡 — As a Giver abroad (e.g. India), I want links to my local Amazon, so that I can buy and the right marketplace is credited.
  • Amazon OneLink integration in place; dormant until NEXT_PUBLIC_AMAZON_ONELINK_INSTANCE_ID is set and locale programs are enrolled (PR feat(affiliate): Amazon OneLink for international link localization #27).
• 9.4 Cart & checkout ✅ (simulated) — As a Giver, I want a cart and checkout, so that I can assemble and "complete" a gift.
  • /feed/cart + Maxi share a localStorage cart; checkout is a simulated demo — no real payment backend.
• 9.5 Real product details ⚪ — As a Giver, I want official titles/images/prices, so that I can compare before clicking.
  • Pending Amazon PA-API access to enrich amazon-picks.json compliantly.
