/*
 * fee[dB]ack — desktop upgrades for pane windows.
 *
 * In the desktop app a pane window is a real BrowserWindow: it remembers where you
 * put it, it stays off the taskbar, it minimizes to the system tray, and the tray
 * lists every pane you have.
 *
 * Note what this file does NOT do: it does not open the window, and it does not
 * close it. That stays in pane-window-host.js, and it stays `window.open()` —
 * because the pane's element is MOVED into that window's document, and a window
 * the main process created for us would give this realm no handle to adopt into.
 *
 * Electron turns our same-origin `window.open()` into a real BrowserWindow anyway,
 * and the main process recognises it by its frame name (`fbpane-<id>`) and takes
 * over the OS-level behaviour from there. So the only thing left to say across IPC
 * is "here are the panes that exist" — for the tray — and to listen for the tray
 * saying "open that one".
 *
 * In a browser, or on an older desktop build, this file does nothing and pop-out
 * works anyway. Everything here is an upgrade, not a dependency.
