Similar to what I do. I use a mini camera on a child's microscope,
modified to work over a large area. Works brilliantly, once you get used
to looking at a TV screen, instead of what you are working on.

That was the bit I thought might get some 'getting used to' ;-)

One big
improvement might be a small powered laser to pin point the centre of
the view. That way, you can set up your tools within the point of focus
and then home on into it, when you look to the screen.

Sounds like nanobot construction! ;-)

Going back to the O.P. What you need is a very narrow soldering iron tip
that is tapered to a point, that way, it looks a bit less than a
scaffold pole.

Well in the flesh this is the 'pointyest' soldering iron tip I've ever
used but the tip diameter was still probably 2x the width of each of
these tracks? 1 strand of some thin multicore copper wire was the same
size as the tracks?

Interesting stuff though ...

All the best ..
