+// During `./gradlew allTests` many wasmJs/js browser test tasks start a
+// ChromeHeadless instance at the same time. On a loaded machine the browser
+// can take longer than Karma's defaults to capture or to emit progress, so
+// Karma disconnects it ("Disconnected, no message in 30000 ms" /
+// "ChromeHeadless was not killed"), ends up discovering zero tests and the
+// build fails on Gradle's `failOnNoDiscoveredTests` check — even though the
+// tests pass fine when the task runs in isolation.
+//
+// Generous capture/disconnect/no-activity timeouts plus a few disconnect
+// retries make the run wait patiently for a starved browser instead of
+// giving up. Kotlin's Gradle plugin merges every *.js here into karma.conf.js.
