 did the trick.  pain doing them by hand, had to do the flood-fill,
then adjust the keepout, then write down by hand the distances that
the keepout fitted cleanly to the edges, _then_ throw that file away,
_then_ go back and put the rectangle left-right... bletch :)

 anyway i moved the PWM via up a bit, left the 3V3 VIAs where they
were - sorted.
