Binning of the gluon fusion production process, the electroweak production process (combines $\mathrm{VBF}$ and ${\mathrm{V}}_{}^{}\mathrm{H}$ with hadronic ${\mathrm{V}}_{}^{}$ decay), the ${\mathrm{V}}_{}^{}\mathrm{H}$ production process with leptonic ${\mathrm{V}}_{}^{}$ decay (combining $\mathrm{W}\mathrm{H}$, $\mathrm{Z}\mathrm{H}$, and gluon fusion $\mathrm{Z}\mathrm{H}$ production), and the ${\mathrm{t}}_{}^{}{\overline{{\mathrm{t}}_{}^{}}}_{}^{}\mathrm{H}$ production process in the merged stage 1.2 of the STXS framework used in the $\mathrm{H}\to \mathrm{Z}\mathrm{Z}\to 4\ell$ analysis
