What problem does this feature solve?

Currently, different subdomains share exactly same resources with different URLs:

• https://meta.cmty.io/_nuxt/views/members/member.9cc289019ef214cd52ff.js
• https://nuxt.cmty.io/_nuxt/views/members/member.9cc289019ef214cd52ff.js

A CDN can easily serve _nuxt directory under cdn.cmty.io so users have faster page loads when working with different cmty communities.

What does the proposed changes look like?

    build: {
        publicPath: process.env.BUILD_PUBLIC_PATH
    },

And then set BUILD_PUBLIC_PATH to https://cdn.cmty.io on Heroku.

Additional: PWA + Workbox may help more improvements too :)
