// glm is header-only. Including it inside the module purview attaches its
// declarations to this module, which is what lets them be exported. Every other
// module imports this one instead of including glm directly: GCC 16 rejects the
// merge when the same glm declarations arrive from several different modules
// ("conflicting imported declaration" on glm::detail::storage), so glm has to be
// compiled into exactly one module.
// Clang warns that including inside the purview attaches the declarations to
// this module. That is exactly the point here, so silence it for this block.
