void drawBatch(Canvas canvas, Paint paint, Color baseColor) {
  // Sort by opacity to ensure consistent ordering
  final sortedOpacities = linesByOpacity.keys.toList()..sort();

  for (final opacity in sortedOpacities) {
    // Update paint color once per opacity level
    paint.color = baseColor.withAlpha(opacity);

    // Draw all lines with this opacity
    final lines = linesByOpacity[opacity]!;
    for (final (p1, p2) in lines) {
      canvas.drawLine(p1, p2, paint);
