That band at the bottom was not a background mismatch — the canvas was transparent there. render() never cleared: the stands cover the top and the out-area quad covers the middle, so it looked complete, but the quad only reached z=30 and everything below where that projects was see-through. The page showed through it, which is why it read as a slightly duller green. The frame is now cleared to pal.out before anything draws, oversized by 8px so a camera shake cannot expose an edge, and the out-area quad runs to z=60 so the perspective floor reaches the bottom on any aspect. Verified by sampling alpha down the bottom third: opaque everywhere, one uniform colour, matching the page gradient behind it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
