// The C factory function in GeoPackagePluginInfo.cpp is annotated with
// __attribute__((visibility("hidden"))) and the GeoPackage CMake target
// ships with CXX_VISIBILITY_PRESET=hidden / VISIBILITY_INLINES_HIDDEN=ON.
// Together these prevent the dlsym leak that PluginFactory::discover()
// was picking up on the engine's SHARED binary.
//
// Hosts that need the GeoPackage plugin should obtain it via the
// PluginFactory (it is now registered as a built-in in
// register_builtin_infos when OPENSWMM_HAS_GEOPACKAGE is defined) or via
// openswmm::discover_plugins_by_id() — NOT via dlsym on the engine
// library. See §R.3 of GUI_IMPLEMENTATION_PLAN.md (in the
// openswmm.gui repo) for the full rationale.
