REM wait-gateway.bat - fallback watcher after Windows-Start opens loading.html.
REM Slow USB drives can need tens of seconds before the gateway listens.
REM
REM Windows-Start opens Config Center immediately, so the ready path only
REM exits quietly. On timeout, reopen Config Center as a recovery hint.
REM Usage (called in background by Windows-Start.bat): wait-gateway.bat PORT CONFIG_PORT
REM Polls every 2 seconds, up to about 5 minutes.

REM Use ping (not "timeout /t") for the ~2s delay: if a GNU coreutils "timeout"
REM is on PATH (Git/MSYS bin), it rejects "/t" and this poll becomes a busy-loop.
REM ping for the delay is PATH-robust and matches Windows-Start.bat's wait loop.
