Subject: [PATCH] Implement multi-layer fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cover image for anything that's not home (with fallback to favicon where cover is not set), and for anything that is home we use the favicon with fallback to the default color block
