The `styleGuide/` folder includes:
* a base set of style rules and conventions for littleware web apps (colors, fonts, etc)
* a styleGuide javascript module that integrates littleware style conventions
into components and applications
* a nunjucks `basicShell.html.njk` template that manages the asynchronous
initialization of an application page, and registers a service worker
