Oh, it appears, upon closer inspection, that the rounded edges belong to the “rear” of the component. The rear is facing the heat sink side and the other or front is facing the speaker side.

Weird. Mine looks like it is installed per the silkscreen. But mine works so it must be installed correctly.

I’m concerned now my assembly was incorrect
Compare to this photo that shows the orientation of Q2 in the context of adjacent components, as long as it's installed this way, you're good to go regardless of what the silk screen says:
It also won't work if it's backward. My board is an early one, I assumed the silk-screen was corrected on later ones. My other comments on the Nouveau 75: https://tinyurl.com/w5saw83
