* When triggered, it prevents the default behavior and toggles the
* `detect-made-by-ai` class on the `<body>`, which can be used to apply visual
* indicators or filters on AI-generated content.
*
* If executed outside of a browser environment (e.g., in Node.js), the function logs an error and exits.
* If the `<body>` is not available at the moment the shortcut is triggered, a warning is logged.
*
* @param {string} [key='a'] - The lowercase character key to be used in combination with Ctrl and Alt.
