Unity: how to embed a VR Cardboard game into a website

Question

Right now, I think there is no way in Unity to do this. This is what I have found so far (please correct me if I am wrong):

The most popular VR plugins compatible with Unity for Android and iPhone, Durovis Dive SDK and Google Cardboard SDK .
I read that most Android phones are compatible with these VR plugins. My experience is that some of them are compatible. The Durovis Dive SDK seems the most compatible at the moment. If the Android phone does not have a gyroscope and the game has the Google Cardboard SDK plugin, the game will not load or crash. If there is no gyro on the Android phone, the game will be downloaded, but the image will be still when we move the phone.
Unity 5.3 has just been released. It includes support for WebGL . It includes VR support . Support for Samsung Gear and Occulus . However, I did not learn anything about compatibility with other Android or iPhone devices. Perhaps it works (I did not test it. I did not find the one who still has the test).
There is a list with VR technology for the Internet .
We can find material to export the Unity scene to Three.js . Scripts and animations don't seem to work.
