The shared shell for every framework error page.
Rules that are load-bearing, not stylistic:
* Every byte is self-contained — no stylesheet link, no font link, no
script, no image. These pages render when the database is down, when
the static pipeline is unbuilt, and when collectstatic has never run.
An error page with an external dependency fails exactly when it is
needed.
* The palette is the shipped auth identity (mojo-auth-theme.css), copied
here as literal values rather than imported, for the reason above. Keep
the two in step by hand if the auth tokens ever move.
* Light/dark follows the visitor's system preference only. There is no
toggle and no cookie: an error page has no session to remember one in.
* Nothing here interpolates request data. The only context values are the
wordmark and, on 500, an incident reference.
