QUOTE `{}`	Atmospheric retrievals yield strong evidence for H2O and CO2 with Bayes factors of log10 B_H2O=8.9 and log10 B_CO2=52.3, while providing tentative evidence for H2S (log10 B_H2S=1.4).
QUOTE `{}`	The joint H2O and CO2 constraints favor an atmosphere near chemical equilibrium, with log10 M/H=0.99^{+0.19}_{-0.14}, corresponding to ~10× Solar or ~9× relative to the near-solar metallicity host star, and a 3σ upper limit of C/O <0.52.
QUOTE `{}`	We find no significant evidence for clouds; instead, the persistence of molecular structure across the spectrum argues against strong cloud muting.
