Overview

Wires the Athena (Ember) theme into a host ActiveAdmin 4 app:

- vendors the token/component CSS into app/assets/tailwind (out of the served path)
- imports it into the AA tailwind build
- registers the gem's views as a tailwind content source (so partial classes scan)
- copies self-hosted fonts to public/athena-fonts
