// imprint.el — L3 Imprint layer (stub — full implementation in feat/layer-imprint)
// Routes the processed input through the active imprint and generates the final reply.
// This stub allows soul.el and routes.el to compile while feat/layer-imprint is pending merge.
//
// Contract for imprint_current() -> String:
//   Returns the active imprint ID (node ID from engram), or "none" if no imprint is loaded.
//   Used in health checks and to identify which imprint L2/L3 should operate against.
//
// Contract for imprint_respond(input, imprint_id) -> String:
//   Generates a reply from the active imprint given the stewardship-aligned input.
//   Falls back to handle_chat when no imprint is active (imprint_id = "" or "none").
