Squared sound speed ﹩{c}_{s}^{2}﹩ (top) and trace anomaly Δ = 1/3 − p/ε (bottom) as functions of baryon density, with n_L = 25 n₀ in the left column and n_L = 12 n₀ in the right column. Filled bands give the 68% credible intervals, and solid lines mark the median values, with FOPT shown in blue and NPT in red. Black dashed lines indicate the conformal references ﹩{c}_{s}^{2}={c}^{2}/3﹩ and Δ = 0.
