One-flavon flavor: A single hierarchical parameter $B$ organizes quarks and leptons at $M_Z$

Flavor hierarchies emerge from a single hierarchical parameter $B$ in a one-flavon Froggatt–Nielsen scheme. Fixing $B=5.357$ from charged-lepton ratios ($m_e:m_{\mu }:m_{\tau }\text{\hspace{0.17em}⁣}\propto \text{\hspace{0.17em}⁣}{\epsilon }^5:{\epsilon }^2:1$, $\epsilon =1\mathrm{/}B$), we reproduce quark masses and CKM targets at $M_Z$ with $\text{ordone}$ coefficients. The same $\epsilon$ gives viable lepton textures and benchmarks for $U_{\mathrm{P}\mathrm{M}\mathrm{N}\mathrm{S}}$, $\sum m_{\nu }$, and $m_{\beta \beta }$. Compact correlations ($\mathrm{\mid }{V}_{us}\mathrm{\mid },\mathrm{\mid }{V}_{cb}\mathrm{\mid },\mathrm{\mid }{V}_{ub}\mathrm{\mid },{\theta }_{13}^{\mathrm{P}\mathrm{M}\mathrm{N}\mathrm{S}}$) follow from powers of $\epsilon$.
