Restore Japanese-glyph logo shape with evened bars

The uniform-thickness pass had dropped the bars' left overhangs, turning
the logo into a pinwheel (swastika-like). Restore the original
firehawk.sc5 layout — a vertical spine crossed by two bars that overhang
it on both sides, plus a hanging lower-right stroke — but even out the
weights: both bars and the leg are a uniform 6px, with the spine slightly
thicker (8px) to keep the original glyph's character.
