Thanks so much for all the great advice I knew was here, allowing me to remedy this problem today.
The dishing was the issue, as I should've mentioned I recently replaced each spoke one at a time, since I've never done any sort of wheel building. This must've caused the dishing to go off center. Flipping the wheel around showed at least 5mm off center. Taking the 1/4 turn advice, which took several stages, I've moved the wheel over and it's now centered perfectly permitting an ideal fender line and alignment. Each time I've tried something I'd normally take to a shop, I realize there's so much more I can do at home and enjoy it at the same time.
