-** Summary: changing to `double` reduces the wasm file size by a mere
-** 2k.  It is hypothetically not possible that any clients rely on
-** doubles larger than 64-bit because there is no mapping between C
-** and JS for them. i.e. we "could" switch LONGDOUBLE_TYPE to double
-** for wasm builds with very little risk of problems. Clang 18.1 maps
-** `long double` to float128 but Emscripten doesn't (cannot) expose
-** that to JS.
