I've been working on pretty much the same thing (IVI ui) and I take a
somewhat similar approach. I create a set of reusable components that
are all dependent on a central style object which is just a QtObject
{}  with a bunch of properties and some helper functions. It has
colors, fonts, and some basic dimensions I use for components and
layouts in my QML files. It works well -- you just need to have the
style object visible to all your pages.
