NOTE: Blocked on T319447
== Background
We would like to add a toggle that controls the width of the site for the Vector 2022 skin
== Design
Prototype: https://di-full-width-toggle.web.app/Galaxy TBD: precise location of the toggle
| | Limited width on | Limited width off
| -- | -- | --
| Article (top of page) | {F35611232 width=400} | {F35611234 width=400}
| Article (scrolled) | {F35611245 width=400} | {F35611240 width=400}
| Special page (that is "full-width") | {F35611236 width=400} | {F35611238 width=400}
==Acceptance criteria
[] Build a toggle that expands the fixed width of the page
[] This behavior would be persistent for logged-in users and not persistent for logged-out users
[] The toggle should appear around 1600px and be hidden below that breakpoint.
[] No changes are required for the existing logic of Special:RecentChanges / other Special Pages
==QA
[] Ensure that we test the new toggle alongside the help icon for suggested edits [1]
___
[1] Steps to trigger this are:
1) Go to Newcomer `Special:Homepage` (GrowthExperiments should be turned on, if not turn on all at Preferences > User Profile > Newcomer editor features)
2) Select a "Suggested edits" task that is *NOT* machine assisted (eg., Copy edit)
You will be taken to the suggested article to copyedit in Read mode, with the floating Help panel icon visible.
