I stumbled upon this FIXME while testing my changes prior to this and
realized that can't possibly be right.
So, I corrected it and also changed the text while at it.
The new design focuses on the Vizio page, but includes a new theme for
the rest of the site as well. All of these changes were both designed
and implemented by Meredith Thompson <merethom@pm.me>.
Each Cast (episode) can belong to one or more Podcast, allowing episodes to be
shared between podcasts. This enables us introductory episodes to be delivered
in their own feed, but also included in the main "The Corresponding Source"
feed.
This required adding an additional `podcast_slug` argument to most views. The
date archive views were dropped because they're not linked to from anywhere.
Added a `podcasts` view as an index of all available Podcasts.
