Composes withPer-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.
ReliabilityNot a free tier in the storage sense - 'included storage' is bundled into a paid daily rate. Over the registry storage limit requires Azure Support.
