Undefined Behavior Desk Mat

A large-format desk mat for developers who have made peace with the idea that certain outcomes are technically possible without being technically guaranteed. The mat is stable. Your code is stable. Whether they are stable for the same reasons remains to be seen.

90cm x 40cm. Stitched edge. Non-slip rubber base. Micro-textured surface. UNDEFINED BEHAVIOR printed in small type along the bottom edge in a colour that can be described as 'the feeling you get when a test passes for no reason'.
