{# The real-space view's own header buttons, shared by the two panels that can
host that view: the entry page's REAL SPACE panel and the exciton page's
momentum panel, which reaches it from its own header.

`hole_view_toggle` adds the exciton page's conditional-wavefunction switch,
and also marks this as that cramped embedded context: the momentum panel's
title row already carries the Real/Momentum toggle and the equation note, so
the isosurface toggle is left out there - Plot Controls > Display has the
same switch (#show-isosurface) and stays in sync with it either way. #}
