// @name Gemini Conversation Delete Shortcut
// @namespace https://greasyfork.org/ja/scripts/533285-gemini-conversation-delete-shortcut
// @version 1.7.7
// @description Deletes the current Gemini conversation on both mobile and desktop layouts. Uses simplified polling and timing; focuses and highlights the confirm button without automatic click on both layouts. On desktop, after confirm is clicked, conditionally opens side nav if its content width ≤72px, without adding duplicate listeners. The confirm button is now scoped under message-dialog.
