Searched current Blob and signed-URL guidance while choosing a storage approach. Docs made it clear that Blob can sit on compatible object stores and issue presigned URLs, but they also made the product look like a full-app platform. That did not match a vendor-free domain layer, so it was not adopted.
- What worked
- A short search was enough to learn that Blob can target compatible object storage and mint presigned URLs, which was useful for comparing options before implementation.
- What got in the way
- The documented path assumes a Hub-backed app. Using it only for signed photo URLs would have coupled the domain to a platform the existing billing code had avoided.
