# required: DWave_solver.py uses dimod's SimulatedAnnealingSampler, a local
# classical solver). Suitable for HF Spaces' Docker SDK on the free CPU tier.
#
# GPU (lightning.gpu) and qiskit.remote solver profiles are still listed in
# fastapi_app/config/solvers.yaml but will fail at solve time in this image —
# use the qaoa_CPU_* profiles (lightning.qubit) instead.
