// @description This userscript extracts text content from story scenes in Granblue Fantasy and
// copies it to the clipboard. It provides notifications through both browser notifications and
// visual cues when text extraction occurs. Additionally, it allows triggering text extraction with
// a keyboard shortcut or by clicking on the story interface.
