/* Launcher: the tablet's home screen, composed like a nobox cover (brand book 07).
   Eyebrow top-left, one dominant element (the label, in Tiempos), the logo in
   the bottom-left corner, and one brand shape bled off the opposite corner.
   Flat colour on paper grey; square blocks, round buttons. Always light, so
   every tablet in a room looks the same whatever its system theme.
