  We image local superfluid density in single crystals of Pd-intercalated
ErTe$_3$ below the superconducting critical temperature, $T_c$, well below the
onset temperature, $T_{CDW}$, of (disordered) charge-density-wave order. We
find no detectable inhomogeneities. We observe a rapid increase of the
superfluid density below $T_c$, deviating from the behavior expected in
conventional Bardeen-Cooper-Schrieffer, and show that the temperature
dependence is qualitatively consistent with a combination of quantum and
thermal phase fluctuations.
