+     * DebugKit configuration.
+     *
+     * Contains an array of configurations to apply to the DebugKit plugin, if loaded.
+     * Documentation: https://book.cakephp.org/debugkit/5/en/index.html#configuration
+     *
+     * ## Options
+     *
+     *  - `panels` - Enable or disable panels. The key is the panel name, and the value is true to enable,
+     *     or false to disable.
+     *  - `includeSchemaReflection` - Set to true to enable logging of schema reflection queries. Disabled by default.
+     *  - `safeTld` - Set an array of whitelisted TLDs for local development.
+     *  - `forceEnable` - Force DebugKit to display. Careful with this, it is usually safer to simply whitelist
+     *     your local TLDs.
+     *  - `ignorePathsPattern` - Regex pattern (including delimiter) to ignore paths.
+     *     DebugKit won’t save data for request URLs that match this regex.
+     *  - `ignoreAuthorization` - Set to true to ignore Cake Authorization plugin for DebugKit requests.
+     *     Disabled by default.
+     *  - `maxDepth` - Defines how many levels of nested data should be shown in general for debug output.
+     *     Default is 5. WARNING: Increasing the max depth level can lead to an out of memory error.
+     *  - `variablesPanelMaxDepth` - Defines how many levels of nested data should be shown in the variables tab.
+     *     Default is 5. WARNING: Increasing the max depth level can lead to an out of memory error.
