      abstract     = {The leptonic decay-constant ratio $f_K/f_\pi$ is calculated
                      from lattice-QCD simulations using $N_f=2+1$ dynamical
                      fermion flavors in the clover-improved formulation and 2-HEX
                      smearing. The simulations were performed for a range of
                      mass-degenerate light quarks including the physical point
                      and at various lattice couplings and volumes, allowing to
                      quantify all relevant sources of systematic uncertainties
                      for our final number of the decay-constant ratio. Utilizing
                      input from chiral perturbation theory, we also quote the
                      charged decay-constant ratio $f_{K^\pm}/f_{\pi^\pm}$. With
                      further input from super-allowed nuclear $\beta$-decays,
                      eventually we obtain an estimate for the CKM-matrix element
                      $V_{\rm us}$.},
