It's tough to distinguish between debris and a faulty pin, so use a magnifying glass.
After further checking, it seems to resemble a tiny fragment of lint or plastic. My vision is fuzzy and the camera has trouble focusing on it due to its size. Could using compressed air be a good idea? What steps should I take to remove it safely without harming anything?
As long as you're not in the socket it should be okay. My approach would involve a steady hand and a few thin tweezers. Testing it in isopropyl alcohol might also work and clear it out, though it isn't certain enough for 100% confidence (it won't harm the board, so it's worth trying).
I plan to use compressed air since I don’t want to risk damaging a pin with tweezers. After having three coffees, I’m feeling energized. Perhaps shaking the mobile first would help determine if it should come out.
