+/**
+ * @brief Event filter that catches QFileOpenEvent URLs matching a scheme and
+ *        re-emits them as urlReceived().
+ *
+ * On macOS, when the application is registered as a URL scheme handler, the
+ * OS delivers incoming URLs via QFileOpenEvent on the QApplication object.
+ * Install this filter on QApplication to intercept them:
+ *
+ * @code
+ *   UrlSchemeEventFilter filter(QStringList{QStringLiteral("cockatrice")});
+ *   QObject::connect(&filter, &UrlSchemeEventFilter::urlReceived,
+ *                    &mainWindow, &MainWindow::handleUrl);
+ *   app.installEventFilter(&filter);
+ * @endcode
+ *
+ * Note: the strings are compared against QUrl::scheme(), so they must be
+ * written without the "://" suffix (e.g. "cockatrice", not "cockatrice://").
