What is causing Craft CP assets(JS/CSS) to appear in front-end pages?

Question

Perhaps in some way related to this, I've got a couple of front-end pages on our website that pull in the following files, which seem to all be CP files. These two pages each utilize plugins I've written, each one a different plugin, so there must be something I'm doing in my plugins that calls this stuff in. Any hints?

selectize.css
craft.css
charts.css 
axios.min.js
d3.js
element-resize-detector.js
jquery.js
jquery.mobile-events.min.js
velocity.js
garnish.js
jquery-ui.min.js
jquery.payment.js
picturefill.js
selectize.js
jquery.fileupload.js
xregexp-all.js
fabric.js
Craft.min.js

EDIT: Here is the relevant asset-bundle:

class LivestreamAsset extends AssetBundle
{
    // Public Methods
    // =========================================================================

    /**
     * Initializes the bundle.
     */
    public function init()
    {
        // define the path that your publishable resources live
        $this->sourcePath = "@kr37/livestream/assetbundles/livestream/dist";

        // define the dependencies
        $this->depends = [
            CpAsset::class,
        ];

        // define the relative path to CSS/JS files that should be registered with the page
        // when this asset bundle is registered
        $this->js = [
            'js/Livestream.js',
        ];

        $this->css = [
            'css/Livestream.css',
        ];

        parent::init();
    }
}

Answer 1

those CP files are included by CpAsset asset bundle.

if your plugin asset bundle depends on CpAsset:

class YourPluginAsset extends AssetBundle
{
    public function init()
    {
        $this->sourcePath = __DIR__ . '/dist';
        $this->depends = [
         CpAsset::class,
        ]
     //....
    }
}

and if you register your plugin asset in frontend or backend template:

{% do view.registerAssetBundle("ns\\prefix\\YourPluginAsset") %}

or via controller:

 $this->view->registerAssetBundle(YourPluginAsset::class);

those file are added to that page automatically.
