Space Crop Life-Support Balance Lab (2D)

This 2D companion swaps the 3D version's orbiting hydroponic hardware for the actual bioregenerative math behind it: a Michaelis-Menten light-response curve sets how fast each leaf fixes carbon under the chosen LED intensity, a logistic canopy-growth curve fills in leaf area over the chosen grow-cycle length, and a real O2/CO2 mass balance — crop gas exchange against fixed NASA crew consumption rates — tells you in real time whether the chamber you've configured is actually large enough, bright enough, or has grown in far enough to keep its crew's air breathable.
