Deep-Time Ceiling Engine: Interactive Elemental Throughput Simulator

This interactive simulator implements the elemental throughput framework described in “Why Growth Stops Before Saturation: Elemental Throughput Limits in Deep Time” (Zenodo DOI: 10.5281/zenodo.18655090). The tool allows users to vary replenishment rates, irrecoverable loss fractions, and per-unit elemental inventories to explore steady-state ceilings imposed by replacement dynamics. The simulator illustrates how sustainable infrastructure scale is bounded by the minimum replenishment-to-loss ratio across required elements, independent of stellar energy availability.
