How long an unreferenced blob must sit untouched before it can be collected.
A client PUTs every blob BEFORE writing any hash into the doc, so there is
always a window in which a perfectly good blob has no reference yet. 24h is
far beyond that window while still bounding growth. Referenced blobs are
immune at any age, so this only sizes the race margin, not retention.
