_h2_probe_imgsearch.nx source

1// _h2_probe_imgsearch.nx -- MEASUREMENT PROBE (ten-second-tool, NOT a deliverable; 2// mirrors _h2_fetch_google). The cookieless /search?tbm=isch GET returns 200 but 3// google's "enable JavaScript" interstitial (/httpservice/retry/enablejs) -- so the 4// results are JS-rendered, NOT a cookie/consent wall. This probe now measures the 5// NO-JS google endpoints (gbv=1 basic HTML, asearch=ichunk async image fragment, 6// udm=2 modern vertical) to see which, if any, yields PARSEABLE image results 7// without a JS engine. Fresh TLS+ALPN-h2 connection per path.
