Minimal Genome Designer: Synthetic Cell Viability

Design a synthetic cell's genome from four essential gene modules — replication and repair, core metabolism, membrane and transport, and a stress-response buffer — each with its own real-biology essential floor below which the module simply cannot sustain life. Push the genome toward the bare minimum and doubling time drops but every division risks death; keep a full complement and the colony grows slowly but almost never collapses. A 3D colony of up to 24 cells occupying fixed lattice slots grows, divides and sometimes dies in real time as you adjust the sliders, with live readouts for viability probability, genome size, doubling time and mutational robustness — the exact trade-off synthetic biologists navigate when engineering a minimal chassis organism.
