Firecracker Chain Reaction 2D: Fuse-Burn Kinetics

This side-view simulation follows a string of firecrackers linked by a common fuse: the flame burns down each segment at a fixed rate, jumps the splice to the next cracker if the contact holds, and that cracker's own rapid pressure buildup pops it before (or instead of) relighting the chain for its neighbor. Nothing propagates on a script — the burn rate, splice contact quality and humidity together decide whether the flame makes it to the end of the string or dies out partway, the same way a real damp or poorly-wrapped fuse chain can fizzle outdoors.
