{# `request` must never appear as a FILTER ARGUMENT here. Django swallows
VariableDoesNotExist for a normal `` lookup, but re-raises it
for a filter arg, and django.views.defaults.server_error renders 500.html
with NO context at all. The old `None | MP4.to` meant
every 500 on this box crashed again inside the error page, so the log only
ever showed the error page's traceback and the ORIGINAL exception was never
recorded -- 110 masked events before 2026-08-09. Same for 404.html. #}
