Fixed: the icon's digits were one shape rather than seven lit segments — every
segment overlapped the one beside it at the corners, which reads as a digit in
dark ink on a white plate and as a blob wherever the drawing is painted light on
a colour, as a themed home screen does. The segments now stand apart, and stay
apart under the outline a launcher adds.

Fixed: the themed icon's wordmark is set in the regular face rather than the
bold one, so it arrives at the weight the app icon has.
