== Background
We decided that a good way to explore the vector codebase is to begin with building a throwaway feature that we can later remove or iterate on. This is our first attempt at doing this
== Acceptance criteria
Build the new header within the vector skin
- must be feature flagged
== Design
{F31057253 width=500}
as in: https://wikipedia-vue-protoype.netlify.com/en/wiki/moon (without the collapsible sidebar)
== Questions we'd like to answer
* What difficulties did you run into while trying to maintain the existing Vector?
* What small improvements could be made beforehand that would have made hacking on this easier?
* What code smells did you encounter while hacking on this?
* What issues with caching (if any) did you run into?
* Do you have any recommendations on how to split up the code to support working on the new mode and the existing mode?
