"""
Every visualization here is native (plain matplotlib/numpy) -- no Qiskit
anywhere in this module. The circuit diagram was already native
(dashboard_core.circuit_diagram); histogram/Q-sphere/Bloch spheres are
now native too (dashboard_core.state_visuals), replacing
qiskit.visualization.{plot_histogram, plot_state_qsphere,
plot_bloch_multivector} -- the last Qiskit call sites this dashboard had.
Qiskit's macOS instability was never proven scoped to just
QuantumCircuit (see circuit_diagram.py's own docstring), so making these
three merely "optional" instead of actually removing Qiskit would have
left the same open question for a different set of functions; there's no
reason left to keep it as a dependency here at all.
