- DagKind::Output (new enum): terminal sink; compiler wires fragColor to its source_ids[0] - dag_catalog: "output" node (1 input, red) - dag_compile: skips Output in node_<i> emission; final fragColor resolves from Output's connection - dag_node_editor: no more Add button; drops "DAG_NODE_TYPE" payloads at mouse canvas position; Output cannot be deleted; Output has no output pin - dag_palette (new fn): Functions window with grouped, draggable node cards - main.cpp: "Functions" window added; ensure_dag_default seeds plasma + connected Output
