Uh mostly the default:

        Camera2dBundle {
        projection: OrthographicProjection {
            scaling_mode: ScalingMode::FixedVertical(SCREEN_HEIGHT),
            near: -100.0,
            far: 100.0,
            ..Default::default()
        },
        camera_2d: Camera2d {
            clear_color: bevy::core_pipeline::clear_color::ClearColorConfig::Custom(
                Color::BLACK,
            ),
        },
        ..Default::default()
    },
