import type { Logger, LogLevel } from './logger.types.js';
/**
 * Universal console-based logger.
 *
 * Works in Browser, Node.js, and Edge environments.
 * Safe for environments without `console` (silently skips logging).
 *
 * @remarks
 * - Implements the Logger interface with mutable `level` property
 * - Uses native console methods (console.error, console.warn, etc.)
 * - Respects the current log level for filtering output
 * - Level can be changed at runtime via the `level` property
 *
 * @example
 * ```typescript
 * // Create with specific level
 * const debugLogger = new ConsoleLogger('debug');
 * debugLogger.debug('Detailed info'); // Will be logged
 * ```
 *
 * @example
 * ```typescript
 * // Default level ('info')
 * const logger = new ConsoleLogger();
 * logger.debug('Not logged'); // debug < info
 * logger.info('Logged'); // info = info
 * ```
 *
 * @example
 * ```typescript
 * // Change level dynamically
 * const logger = new ConsoleLogger('error');
 * logger.info('Not logged'); // info < error
 * logger.level = 'info';
 * logger.info('Now logged'); // info = info
 * ```
