Per-object cap	not stated
Retention	Basic is ~$0.167/day even with the included 10 GiB; rate limits by SKU return HTTP 429 with Retry-After; 12-month free Standard expires into billing. (360 days)

Tooling	ORAS / docker push / skopeo against <registry>.azurecr.io; OCI artifacts let you push arbitrary blobs, not just images
Composes with	Per-registry included storage is a paid SKU line item, not a free quota - the 100 GiB is 'included in the daily rate', so extra storage bills per GiB/day. N registries x 100 GiB is N paid registries.
Reliability	Not a free tier in the storage sense - 'included storage' is bundled into a paid daily rate. Over the registry storage limit requires Azure Support.
