I know what fiducials look like, but haven't seen a "footprint"
for one within pcb.  Am I blind?  Is there a standard recipe for
making one?

The last time I asked a board loading house about fiducials, they
said they gave up and just optically register to the component
footprint itself.

This is something I have never gotten into.  I guess my boards
are always too large and/or the order too few to care.
