How long a superseded page may still be answered, in ms.
A row is served while its age is below this, so 0 is a real off switch. 60 s bounds the drain
window rather than setting freshness: a page still aged after a minute means the refill chain
stopped, and that should be a 503. Tighter than the KV tier's STALE_MAX_AGE_MS (24 hours,
answered from a previous generation).
