+# Use the system Lua from the declared Build-Depends (liblua5.4-dev) instead of
+# the bundled lua subproject wrap, so the build works offline and exercises the
+# declared dependency (including for cross-builds). freetype2 and pcre2 are also
+# resolved from their -dev packages via pkg-config, so no wraps are fetched.
+# Note: do NOT pass -Dwrap_mode here; some build drivers (e.g. pkh) already pass
+# --wrap-mode on the meson command line, and Meson errors out if the same option
+# is given in both forms.
