Script Injection POC

0 of 0 as expected

Leave page (then hit back → bfcache test)

Each test injects code that sets window[sentinel] = true. After a short tick we read the sentinel and compare to expectation. Results are stored in localStorage under script-injection-poc-v1. Sentinels use per-run unique keys so re-runs don't see stale state. pageshow tells us whether the page came back via bfcache (relevant on iOS Safari).
