The triangle was mine. Extending the out-area quad to z=60 put it past camZ (48), and proj() divides by (camZ - z) — so the scale explodes at the camera plane and goes negative beyond it, folding the quad's far edge back above the screen. The quad goes back to z=30; the full-frame clear is what covers the screen, so it never needed extending in the first place. The bottom still not being green was a second bug, in the previous commit. The gradient was set on body, but the ROOT element's background is what paints the viewport, and index.html gives html a background too — so body's never propagated and painted only its own box, which has no height because the canvas is position:fixed. It goes on documentElement now, and html gets an explicit height, because a gradient is laid out in the root's own box and that box collapses for the same reason. Verified with the canvas deliberately ending 40px short: root box fills the viewport, gradient's lower stop is rgb(41,92,45), the canvas's bottom row is the same, and the seam is invisible.
