+# No library backend for v1. `static` (not `off`): `off` leaves `libsSource` null so boot.ts
+# never calls installLibsProvider → `window.kicadLibs` is never installed → any C++ path that
+# resolves a symbol/footprint through the libs bridge on schematic open (park site K1,
+# sch_io_pcbjam_lib) calls a method on undefined → throws inside a suspending import →
+# SuspendError → abort. `static` installs the bridge backed by 2 built-in example symbols; it
+# answers "not found" gracefully for everything else. No backend, no manifest, self-contained.
