# Runtime dependencies for the mine throughput simulation.
#
# Allowed libraries (prompt.md constraint):
#   simpy, numpy, pandas, scipy, matplotlib, networkx, pyyaml
# Pillow is a transitive matplotlib dependency used by FuncAnimation when
# rendering animation.gif; it does not need to be listed explicitly.
#
# Lower bounds are given (rather than exact pins) so the model installs
# cleanly across the supported Python range (3.11-3.13). The conceptual
# model and numeric outputs do not depend on patch versions.
