#!/usr/bin/env node
// Slice ONE pipeline out of a toggle-template pack workflow into a standalone,
// activated graph. Thin CLI wrapper around the shared sliceWorkflow() service
// (src/services/workflow-slicer.ts) — the same implementation that
// get_workflow (action:"slice") and panel_slice_workflow use.
//
//   node scripts/slice-pipeline.mjs <src/workflow.json> <out.json> "<grpA>,<grpB>,..."
//
// Group args are case-insensitive substrings of group titles whose output nodes
// seed the slice (shared post-proc like UPSCALE/GRAIN/SHARP are pulled in
// automatically via the closure). Verify the result with verify-render.mjs.
