[sdiy] No marking on resistors

Cheap fabs too. None of the usual China-based "$10 for 10x 100x100mm
2-layer 1.6mm PCBs" fab shops I've used in the last 5 or so years has ever
given me boards back where the silkscreen contaminated pads

Seeed Studio definitely don't. Have sent them maybe 30 or 40 sets of
Gerbers so far, and TBH while I try to keep silk away from pads in my
layouts (what's the point in chopping off part of a label anyway? Seems
counter-productive) I'm not exactly OCD about it
