+///     broadcaster → Blazor <c>/script-log</c> page pipeline (Layer 0 of the script-log /

+///
+///     <para><b>Scope note:</b> mirrors <see cref="DriverStatusHubE2eTests"/>. The Blazor circuit
+///     itself can't be exercised from an integration test (it needs an HTTP listener, JWT auth, and
+///     a real WebSocket upgrade — covered by the manual runbook). This suite instead exercises the
+///     exact server-side delivery the page depends on: it spawns a
+///     <see cref="ScriptLogSignalRBridge"/> in the harness actor system, publishes a
+///     <see cref="ScriptLogEntry"/> to the <c>script-logs</c> DPS topic, and asserts that the entry
+///     reaches the <see cref="IInProcessBroadcaster{T}"/> singleton resolved from the SAME DI
+///     container the <c>/script-log</c> page injects from (plus the SignalR hub push). This is the
+///     link the existing <see cref="DpsScriptLogPublisherTests"/> (publisher → topic) and
+///     <see cref="InProcessBroadcasterTests"/> (broadcaster → subscriber) tests do not cover
+///     together: bridge subscription → broadcaster fan-out off the live topic.</para>
