// Cmd+C works in every window, not just the first (ENG-289).
//
// The app never called setApplicationMenu, so macOS was left with Electron's implicit default and
// the Edit accelerators were whatever that happened to bind. The menu is process-global while its
// items act on whichever webContents holds focus, so "which window" is decided at keypress time by
// role dispatch, not by whatever window the menu was built next to. Declaring the menu ourselves
// makes that dispatch explicit and identical in the first window and the tenth.
//
// ROLES ONLY, deliberately. A hand-written copy handler has to answer "copy from where", and the
// answer is a focused-webContents lookup that is wrong for a <webview> guest exactly when the user
// is inside one. Chromium already resolves roles against the focused contents, including guests,
// so the correct implementation is the one where we write no logic at all.
//
// macOS only: on Windows and Linux setting a menu paints a visible menu bar this app has never had.
