# aborts with "Could not find application :wx" when the build host's
# Erlang/OTP was configured `--without-wx` (e.g. on the macOS installer
# CI now that the workflow drops the custom wxWidgets build). The Erlang
# source file `src/desktop_wx.erl` already adapts to missing wx headers
# via `desktop_wx_stub.exs`, so a host build without `:wx` simply
# compiles the stub backend.
