We have a new path made from brick pavers. Some grass seed, scattered
over-enthusiastically, has gotten into the spaces between the bricks.

We are looking for a grass killer, preferably a fine solid type that won't
migrate out of the path and kill the grass bordering the edges

If you're in area that has winter ice, sidewalk salt works wonders at
killing plants. I've found out the hard way.
