// IceImportSL, so both the BLL interface and the SL hub/client-contract can reference the same
// shape without BLL taking a dependency on SignalR/ASP.NET types.
//
// Throttled to stage transitions (Parse/MapAndTransform/Validate/Commit), not per-row — the
// pipeline stages (Phase 1) don't expose per-row callbacks, and CLAUDE.md's backpressure guidance
// favors coarse-grained pushes over flooding the client anyway.
