   Global Ping Test (/global-ping-test)
   Shares the Network Test suite's brand palette (network-test.css) for a
   consistent "family" look with /ping-test, /jitter-test, /speed-test, but
   lives in its own file since the data flow here (create a real Globalping
   measurement, poll it, render real per-location results) is fundamentally
   different from that suite's instant client-side sampling.
   Scoped entirely under .gpt-page.
