Google's published guidance figures used as publisher policy defaults,
not as the SDK's cache timeout. The real preload TTL is server-delivered and
unreadable; these millis are only the defaults applied when the publisher
does not configure a window. Public contract: Option 1 — report and hand over
inventory that already exceeds the window; do not auto-discard on poll
(isStaleByPolicy / onStaleByPolicy on the held object).
