final log = Logger('payments');
log.info('processed', fields: {'orderId': 'abc-123', 'amount': 99.95});

// Bound loggers carry context
final reqLog = log.withFields({'requestId': 'req-456'});
reqLog.info('charging card');  // includes requestId

// Zone context flows through async code
withLogContext({'traceId': 'xyz'}, () async {
  log.info('inside trace');  // includes traceId automatically
