This is done because the current column-left and column-right were
actually just floating left and right and making use of float-left
and float-right makes more sense. This also helps with the upcoming
public archives feature which will try to include portico content
with main app content.
This commit removes the need for portico.css to be generated
by the Django pipeline and makes the error page use the css
file compiled by webpack instead.
There's no correct contact that we can list here unconditionally;
previously, we had people emailing zulip-devel@ because their server
was misconfigured.
Addresses #696 enough that it's no longer a priority issue.
Ideally some of these templates should really point to the
local installation's support email address, but this is a
good start.
Exceptions:
* Where to report security incidents
* MIT Zephyr-related pages
* zulip.com terms and conditions
We use this error page for all 5xx errors, so I'm removing the error
number from the text.
