// BatchDialog unit tests: parseUrlBlob, expandWildcard, buildAddBatchParams. Lane GUI.
//
// Red when the clipboard parser stops deduping or starts letting non-URL lines through,
// the wildcard expander mishandles zero-padding or a malformed/ambiguous range, or the
// addBatch params start including an empty optional field or leak queueId into a
// non-"queue" startMode.
