components:  storefront-api:    kind: worker    description: >-      The public HTTP API (wrangler.jsonc, Worker storefront-api). Shoppers browse the catalog, fill      carts and check out; the merchant edits products and uploads their images with the admin      token. Its OrdersService entrypoint is how the other Workers change orders: it is the only      Worker with the database binding. A cron trigger expires unpaid orders every five minutes.      Payments go through the payments Worker; this Worker has no Stripe key.    owns: [src/**]    talks_to:      - { to: db, via: d1 }      - { to: images, via: r2 }      - { to: payments, via: rpc }      - { to: order-events, via: queue }  payments:    kind: worker    description: >-      Worker storefront-payments (workers/payments), the only holder of the Stripe keys. Its      PaymentsService entrypoint creates and cancels PaymentIntents for storefront-api; its fetch      handler takes Stripe's webhooks and settles orders through OrdersService.    owns: [workers/payments/**]    talks_to:      - { to: storefront-api, via: rpc }      - { to: stripe, via: https }  fulfilment:    kind: worker    description: >-      Worker storefront-fulfilment (workers/fulfilment). Consumes order-events, sends each paid      order to the warehouse's shipments API and records the shipment through OrdersService.      Failed messages retry with backoff and end in order-events-dlq after six attempts.    owns: [workers/fulfilment/**]    talks_to:      - { to: storefront-api, via: rpc }  db:    kind: d1    description: >-      The storefront database: products, carts, orders and their lines. Every schema change is a numbered      file in migrations/, applied with wrangler d1 migrations apply.    binding: DB    owns: [migrations/**]  images:    kind: r2-bucket    description: >-      Bucket storefront-images: product images under products/<product>/<hash>.<ext>. A key is      never overwritten, so every image URL can be cached for a year. Public on its custom domain      (IMAGES_URL), where browsers load the images; storefront-api only writes to it.    binding: IMAGES  order-events:    kind: queue    description: >-      Queue order-events: order.paid and order.cancelled, sent by OrdersService when an order      changes state. Consumed by fulfilment (queues.consumers in its wrangler.jsonc). At least      once, so consumers dedupe by order id.    binding: ORDER_EVENTS  stripe:    kind: external    description: >-      Stripe, through the stripe npm package, called only by the payments Worker. It creates a      PaymentIntent per order; the shopper confirms it in the browser with the Payment Element, and      Stripe reports the outcome to the payments Worker's webhook.    package: stripe
