N2 - We provide a geometric realization of the universal enveloping algebra of the fixed-point subalgebra in a quasi-split symmetric pair of sln (C), and its idempotent version, in the convolution algebra of constructible functions on Steinberg ind-varieties of classical type. We construct semicanonical bases for the idempotent version.
