[next-devin]

Builds on the existing Shop Pay Admin API guide. Nothing already on the page changes except the setup callout.

Added

• Setup callout: links to the merchant Shop Pay page, which covers connecting an account under Settings > Payments > Shop Pay.
• Capture and Refunds (new section):
  • Shop Pay always authorizes at checkout, and Shopify holds the authorization for 7 days.
  • Capture is full amount only.
  • Refunds can be full or partial after capture, and can come back as pending.
  • Refunding an order that hasn't been captured voids the whole authorization.
  • Disputes are handled in Shopify admin.
• Campaigns API (new section): shop_pay is accepted (it's in the Campaigns v1 spec) and must be enabled on each campaign.

Before marking ready

• Confirm that Campaigns App funnels take Shop Pay in production, with one test order on a campaign.
• Confirm the "refunding before capture voids the whole authorization" behavior is something to state publicly rather than something to fix.

Companion merchant pages, both merged: NextCommerceCo/docs#71 and the Shop Pay launch guide.
