 * The main ASCIIGround class that orchestrates pattern generation and rendering.

 * @example Creating and controlling an ASCII animation
 * ```typescript
 * const asciiGround = new ASCIIGround();
 *
 * // Initialize with canvas and pattern.
 * asciiGround.init(canvas, pattern, options);
 *
 * // Control animation.
 * asciiGround.startAnimation();
 * asciiGround.stopAnimation();
 *
 * // Update configuration.
 * asciiGround.setOptions({ fontSize: 14, color: '#667eea' });
 *
 * // Clean up when done.
 * asciiGround.destroy();
 * ```
