"""Every portal page must actually render.

Nothing in the suite was rendering the ops or portal HTML pages, which is how a
view can lose a line — a `template_name`, say — and 500 in front of a user while
68 tests still pass. These sweeps fetch each read-only page with an empty
database, so they cover the empty-state branches as well as the templates.
