/* Nero standalone shell (Eclipse Preview). Black background. The private screens own the z band 400-460; the shell sits under it
   (menu 200-201, backdrop 205, drawer 206, sheets 210, unlock 212, toast 215, lock fade 399) and the private screens step down
   to 199 (.x-down) while the drawer or a sheet is open; fades 450 ms (reduced motion: 400 ms linear, no movement); small text at 70%. Also the base looks
   the private screens build on (.nsheet .sec .row .tog .sm button.pri), so nothing comes from another app's stylesheet. */
