Hi 🙂  
It looks like a very recent update to Discourse Core (over the June 6–7 weekend) has introduced a breaking architectural change that causes the `discourse-custom-wizard` plugin to crash the entire application boot cycle.

Even attempting to visit `/safe-mode` fails with a global 500 error because the crash occurs during initialization middleware registration.

Here is the exact fatal error trace pulled from Logster:

```plaintext
ActionView::Template::Error (undefined method 'admin_stylesheets' for class DiscoursePluginRegistry)
lib/stylesheet/manager/builder.rb:199:in `Stylesheets::Manager::Builder#plugins_digest'

```

It appears that during the asset/stylesheet compilation phase (`plugins_digest`), core Discourse is invoking an `admin_stylesheets` method on the `DiscoursePluginRegistry` which is throwing an undefined method exception, likely due to a mismatch with how the custom wizard registers or extends administrative styles.

Disabling the plugin in `app.yml` and running a complete container rebuild allows the forum to boot normally, confirming the crash is isolated to the wizard’s integration hooks.

Could you please look into updating the registry/stylesheet hooks for compatibility with current core changes?

Thanks!
