The post-goto token poll ran a blind 20s wait regardless of whether
page.goto succeeded or threw. On a healthy goto the widget API call
fires within ~1-2s; on a failed goto the request either already went
through (rare) or never will (common). The 20s cap was the dominant
cost on failed-site attempts — verified tonight as a 28s "No token
after ..." log on auto-komplekt after page.goto ERR_TIMED_OUT.
* CAPTURE_POLL_AFTER_OK = 10 (5s) — token usually arrives in <2s
* CAPTURE_POLL_AFTER_FAIL = 4 (2s) — brief grace then bail
Per-attempt worst case on a dead site: 10s goto + 2s grace = 12s
(was 10s + 20s = 30s). On a healthy site, well-known capture times
(3-5s) stay comfortably inside the 5s post-goto cap.
