 | The \fcalsum\ distribution in minimum-bias events, together with the thresholds for a few centrality intervals, for (a) \OO\ collisions and (b) \NeNe\ collisions. (c) Comparison to Xe$+$Xe collisions~\cite{HION-2019-03}, where the \fcalsum\ of the \XeXe\ and \NeNe\ systems are scaled by the relative number of nucleons to oxygen. The \NeNe\ and \XeXe\ distributions in panel (c) are normalized to have the same integral as the \OO\ distribution above 30~\GeV. |
 | Correlation between \nchrec\ and \fcalsum\ in minimum-bias events for (a) \OO\ and (b) \NeNe\ collisions, and distributions of \nchrec\ in minimum-bias events for (c) \OO\ and (d) \NeNe\ collisions, including the distributions for several centrality intervals. |
 | Two-particle $\deta-\dphi$ correlations in \OO\ collisions for the (a) 0--5\%, (b) 20--30\%, and (c) 50--60\% centrality intervals. The plots are for $0.5<\ptab<5$~\GeV. The distributions are truncated along the $z$-axis, to suppress the peak at $\deta=\dphi=0$, and are plotted over $|\deta|<4.5$ to avoid statistical fluctuations at larger $|\deta|$. |
 | Template fits to correlation functions measured in \OO\ collisions for the (left) 0--5\%, (center) 20--30\%, and (right) 50--60\% centrality intervals. The plots are for $0.5<\ptab<5$~\GeV. The solid points indicate the measured \ctwophi, and the continuous red line indicates the template fit, $C^{\mathrm{templ}}(\dphi)$. The open points and dashed curves indicate the different components of the template-fit, which are shifted along the $y$-axis by $G$ or by $FC^{\mathrm{periph}}(0)$, where necessary, for presentation. |
 | The $\ptb$ dependence of the \vntpc\ and \vntf\ in the (a,~c,~e) \OO\ and (b,~d,~f) \NeNe\ collisions, for the (a,~b) 0--5\%, (c,~d) 20--30\% and (e,~f) 50--60\% centrality intervals. The solid and open points show the results obtained using the \tpc\ and the template-fit methods, respectively. The vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively. |
 | (a) Flow harmonics $\vntf$ and $\vnfour$ for the elliptic and triangular moments in \OO\ collisions (colored solid markers) and \NeNe\ collisions (open black markers) at $\snn=5.36$~\TeV, shown as a function of $N_\text{ch}$. The \NeNe\ points are slightly displaced along the horizontal axis for visual clarity. (b) Ratios of the flow coefficients in \NeNe\ to those in \OO\ collisions, corresponding to the results in panel (a). Ratios are shown only for the 0--50\% centrality range to suppress large statistical fluctuations in more peripheral intervals. The vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively. For the ratios, systematic uncertainties correlated between the \OO\ and \NeNe\ measurements largely cancel. |

 | Comparison of $\vntf[2]$ and $\vntf[3]$ with theory calculations from the model described in Ref.~\cite{Mantysaari:2025tcg}, for (a) \OO\ and (b) \NeNe\ collisions. The theory calculations are labeled as ``Hydro$+$IPGlasma$+$PGCM.'' For the data, the vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively. The data uncertainties are sometimes too small to be visible. The bands for the theory calculations represent the combined statistical and systematic uncertainties. |
 | Comparison of the measurements to theory predictions for the ratio of (a) $v_2\{2\}$ and (b) $v_3\{2\}$ between \NeNe\ and \OO. The \vntwo\ in the data are obtained from the template fit method. The Hydro$+$Trento$+$PGCM theory is taken from Ref.~\cite{Giacalone:2024luz} and the Hydro$+$IPGlasma$+$PGCM is an extension of Ref.~\cite{Mantysaari:2025tcg}. The ratios are also shown for the eccentricities, a quantification of the elliptic ($\varepsilon_2$) or triangular ($\varepsilon_3$) shape of the initial-state energy density, using the Trento$+$PGCM model. For the data, the vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively. The bands for the theory calculations represent combined statistical and systematic uncertainties. |
 | Comparisons of the (a) \vtwo\ and (b) \vthree\ measured by the template-fit method in \OO\ and \NeNe\ collisions with prior measurements in \XeXe\ and \PbPb\ collisions from Ref.~\cite{HION-2019-03}, as a function of centrality. The \XeXe\ and \PbPb\ results are obtained with the \tpc\ method. The plots are for $0.5<\ptab<5$~\GeV. The vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively. |
 | Comparison of the (a) \vntf[2]\ and the (b) \vntf[3]\ measured in \OO\ and \NeNe\ collisions with prior measurements in \pPb, \XeXe\ and \PbPb\ collisions from Ref.~\cite{HION-2019-03}, as a function of the reconstructed charged-particle multiplicity (\nchrec). The vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively, and are often too small to be visible. |
