@piffy please can you try updating to the latest tests-passed, just in case that `color-input` fix helps at all.

Assuming things are still broken after a rebuild, please can you try this:

```plaintext
./launcher enter app
rails c
Discourse.clear_all_theme_cache!

```

Same goes for you @don, if you have the time.

If that solves the problem, then it suggests we have an issue with the theme cache invalidation 🤔
