   This file is split into clearly labelled sections. Use Ctrl+F (or
   Cmd+F on Mac) and search for a section title in CAPS (e.g. "NAVBAR")
   to jump straight to it.

   You do NOT need to understand all of this to run the site or add
   products — that part happens in js/products-data.js and
   js/applications-data.js, which have their own simple instructions.
