0002 Serve images through storefront-api

Context

Product images are in R2 (see [[product-images]]). Browsers need a URL for each one. R2 can serve a bucket publicly, on its r2.dev subdomain or a custom domain, or a Worker can read the object and return it.

Decision

storefront-api serves images at GET /images/<key>. The bucket stays private.

Consequences

• One hostname for the whole shop while we are still on workers.dev, and nothing to set up in DNS.
• Only keys under products/ are reachable, whatever else ends up in the bucket.
• Every image request runs the Worker, even though the response is the same for a year. That is fine at launch traffic. If image requests start to dominate the Worker's requests, move them to a custom domain on the bucket.
