// Cross-tool file carrying tests

// When a user uploads a file on the home page and then clicks a quick action
// or a tool from "All Tools", the file should be carried to the target tool
// page (no re-upload needed). However, navigating between tool pages via the
// sidebar should NOT carry the file - the tool page resets on route change.
