  We explicitly construct K-theoretic and elliptic stable envelopes for certain
moduli spaces of vortices, and apply this to enumerative geometry of rational
curves in these varieties. In particular, we identify the quantum difference
equations in equivariant variables with quantum Knizhnik-Zamolodchikov
equations, and give their monodromy in terms of geometric elliptic R-matrices.
A novel geometric feature in these constructions is that the varieties under
study are not holomorphic symplectic, yet nonetheless have
representation-theoretic significance. In physics, they originate from 3d
supersymmetric gauge theories with $\mathcal{N} = 2$ rather than $\mathcal{N} =
4$ supersymmetry. We discuss an application of the results to the ramified
version of the quantum q-Langlands correspondence of Aganagic, Frenkel, and
Okounkov.
