+# UI facade — selective re-exports (ADR-025 Phase 3 Layer 2).
+# Previously used `export use <file>.nu *` which propagates the full export graph
+# of each file through every consumer. Selective re-exports keep the facade's
+# convenience (one import gets all UI primitives) while bounding the symbol set
+# so transitivity checks can verify what leaks through.
