/**
 * No-operation logger that produces no output.
 *
 * This is the default logger used when no logger is configured. It implements
 * the Logger interface with empty methods, ensuring zero overhead and no
 * unexpected output when logging is not explicitly enabled.
 *
 * The NoOpLogger allows the publisher to operate silently by default, with
 * users opting in to logging by providing their own logger instance.
 *
 * @example
 * ```typescript
 * // Used internally as default
 * const logger = new NoOpLogger();
 * logger.info('This produces no output');
 *
 * // Users can also use it explicitly if needed
 * publisher.configure(config => config.logger(new NoOpLogger()));
 * ```
