/**
 * AssetManager manages asset bundle configuration and loading.
 *
 * AssetManager is configured as an application component in [[\yii\web\Application]] by default.
 * You can access that instance via `Yii::$app->assetManager`.
 *
 * You can modify its configuration by adding an array to your application config under `components`
 * as shown in the following example:
 *
 * ```php
 * 'assetManager' => [
 *     'bundles' => [
 *         // you can override AssetBundle configs here
 *     ],
 * ]
 * ```
 *
 * For more details and usage information on AssetManager, see the [guide article on assets](guide:structure-assets).
 *
 * @property AssetConverterInterface $converter The asset converter. Note that the type of this property
 * differs in getter and setter. See [[getConverter()]] and [[setConverter()]] for details.
 *

 *     except?: string[],
 *     caseSensitive?: bool,
 *     beforeCopy?: callable,

     * When a bundle is being loaded by [[getBundle()]], if it has a corresponding configuration specified here,

     *
     * The array keys are the asset bundle names, which typically are asset bundle class names without leading backslash.
     * The array values are the corresponding configurations. If a value is false, it means the corresponding asset

     *
     * If this property is false, it means the whole asset bundle feature is disabled and [[getBundle()]]
     * will always return null.

     * When an asset bundle is registered with a view, each relative asset file in its [[AssetBundle::css|css]]
     * and [[AssetBundle::js|js]] arrays will be examined against this map. If any of the keys is found
     * to be the last part of an asset file (which is prefixed with [[AssetBundle::sourcePath]] if available),

     * For example, an asset file `my/path/to/jquery.js` matches a key `jquery.js`.

     * relative to [[baseUrl]] and [[basePath]].
