Content is stored in content files. Content files are in cms folder.
Scoping is very simple. Every page(.hbs file) from pages folder has access to file with the same name in cms folder.
There is a cms/global subfolder. Every content file in this directory is accessible to all pages. Content from global folder is in global object when referencing from handlebars template.

{
name: 'martin'
}
cms/global/car.js
{
car: 'toyota'
}
pagez/index.hbs
<div class="user">{{name}}</div>
<div class="car">{{global.car}}</div>
