"""Mobile status page -- site-first navigation for phones.
The desktop status page is three dense columns; its only phone support is one
media query that stacks them into a single long scroll, which is why field crews
lose their place. This page inverts the model: pick a site, see that site.
It is a LAYOUT, not a second implementation. StatusMobile (status_mobile.js)
extends StatusData exactly as StatusCore (status_desktop.js) does, so the model,
the websocket and every piece of derived state are shared -- the two pages cannot
disagree about whether a generator is running. The gen and pod modals are the
desktop files, included unchanged.
page_key is 'status' on purpose: this is the status page, so anyone who can see
the desktop one can see this, and no user access needs editing.
Not linked from the nav yet -- it is being shown to field crews for feedback
first. Add it to links.py once they are happy with it.
