- GPS was never captured due to race condition: OnAfterRenderAsync checked _client before it was loaded, so the condition always failed - Switched from one-shot getCurrentPosition to watchPosition for continuous GPS tracking during walk tests - GPS watcher starts on first poll (after client identity is known), skips wired devices - Added "Location Permission Denied" banner when browser blocks GPS - Uses DotNetObjectReference for JS-to-.NET callbacks - Properly cleans up watcher via IAsyncDisposable
