      abstract     = {High-energy partons lose energy while propagating through
                      the hot, strongly interacting medium produced in
                      ultrarelativistic nucleus-nucleus collisions, leading to a
                      suppression of particle production at high transverse
                      momentum ($p_\mathrm{T}$). The dependence of this energy
                      loss on the size of the colliding nuclear system has yet to
                      be firmly established experimentally. This Letter presents a
                      systematic study of charged-particle suppression across four
                      different nucleus-nucleus collision systems using nuclear
                      modification factors ($R_\mathrm{AA}$) measured by the CMS
                      Collaboration at the CERN LHC. Previous CMS measurements of
                      $R_\mathrm{AA}$ in oxygen-oxygen, xenon-xenon, and lead-lead
                      collisions are recast with identical $p_\mathrm{T}$
                      intervals and are complemented by the first measurement of
                      the charged-particle $R_\mathrm{AA}$ in neon-neon collisions
                      at $\sqrt{s_\mathrm{NN}}$ = 5.36 TeV. The neon-neon data
                      correspond to an integrated luminosity of 0.76 nb$^{-1}$.
                      The $R_\mathrm{AA}$ in all collision systems examined show
                      similar qualitative trends, but have a magnitude which is
                      ordered with the nucleon number A. The $R_\mathrm{AA}$
                      feature a downward slope at low $p_\mathrm{T}$, a local
                      minimum at around 5$-$7 GeV, and an upward slope with
                      increasing $p_\mathrm{T}$. The $R_\mathrm{AA}$ are also
                      compared in terms of A$^{1/3}$, which is proportional to the
                      nuclear radius. Models including only initial-state nuclear
                      effects fail to reproduce the observed trends, whereas
                      energy loss models reproduce the trends in the region
                      $p_\mathrm{T}$$\gt$ 9.6 GeV.},
