The game decides which cells an item occupies by the alpha of one pixel at the centre of each 16x16 cell. The rig's rack bays left gaps exactly on the centre rows, so 8 of 9 cells counted as empty and other items were placed underneath it; the terminal's stand did the same. The rig gets a solid back plate, the terminal's stand is widened, and art/sprites.py now checks every cell the way the game does and refuses to write a sprite with a hole. Verified in game: new rigs are 3x3 solid, new terminals 2x2 solid. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
