Creates an interactive prototype for gathering
feedback on users typography preferences.
This prototype is meant to be temporary and is
built soley for feedback purposes for the
WMF Accessibility for reading project.
The prototype code is:
- for logged-in users only
- hidden under the API user preference "vector-typography-survey"
- disabled by default
It is intended to be enabled via a banner that calls
code similar to:
new mw.Api().saveOption( 'vector-typography-survey', 1 )
