A stopped VM, an unreachable or unsupported console and a disabled serial console rendered the lite VNC page under the error: it connected to novncd anyway, showed "Something went wrong" and offered keys, Scale and Send CtrlAltDel for a console that was not there. A refused console was a bare text 403 inside the popup. - console-error.html: the console shell with the VM's name and the reason, no menu and no script; a refused or unknown VM gets it with 403 and without the VM's name, as before for everyone (no superuser exception). - The view signs the console token only for a page that connects. - console-menu.html: the Send key(s) menu and Fullscreen, included by the console pages; the serial page lists only the keys it sends (the VNC groups did nothing there). - Every console window is titled "<VM> - Console". - The lite page no longer takes a VNC password from its link. - The shell lost its 850px x 600px corner radius (a grey arc on the serial and error pages) and spans the window (container-fluid).
