banner: artwork is the focal point — plain SKELETONKEY text below

Previous banner had a SKELETONKEY block-letter art that competed
with the skeleton-key drawing for visual attention. Simplified:
the key art is now the focal point, and SKELETONKEY is rendered
as plain spaced text below the drawing.

Slight refinement to the key art: bow is a bit larger (888 instead
of 88) to feel more substantial. Bit/teeth pattern unchanged.

Bump 0.4.2 → 0.4.3.
