?mode=edit&device=mobile
I had argued this one should stay in React state — a way of LOOKING rather than a thing being looked at
— and the distinction did not survive contact with the obvious use. "Here is what it does on a phone"
is exactly the link somebody wants to send, and a URL that drops the width sends them the desktop.
docs/navigation-audit.md already said addressable state goes in the URL. Both of these are addressable.
The rule was right; my exception was not.
Absent means desktop, as absent means view: an ordinary link carries neither parameter, and each
appears once somebody has chosen it.
