Caption: Figure 2.

Left: collated AT 2024wpp optical spectral series spanning from +4.1 to +63.0 days from t₀ (observed frame). Spectra are plotted in the rest frame and are binned for visual clarity (native binning is shown in lighter shading). For comparison, coeval optical spectra of the only other well-sampled LFBOTs, AT 2018cow (R. Margutti et al. 2019) and CSS161010 (C. P. Gutiérrez et al. 2024), are plotted in the middle and right panels, respectively, and identified by the observed-frame epoch of observation. We note that the +4.1-day AT 2024wpp spectrum has an unreliable spectral slope.
