Clarification on theming needed regarding includes

Greetings,

I read the docs (Server Developer Guide) regarding themes and also currently fiddle around with my own theme.

What I’m currently trying to accomplish is that I have a folder in my theme as include area.
So this section (folder) should have CSS and image files in them that I load for all the other sub-themes, like account, login, email, etc.

import itself only imports other themes so that likely doesn’t work.
Is there a way to have this at all?

Current structure be like (the below is not complete as it would be too long):
example-theme.jar:

├── META-INF
│ ├── keycloak-themes.json
│ └── MANIFEST.MF
└── theme
└── example-theme
├── account
│ ├── resources
│ │ └── css
│ │ └── exaccount.css
│ └── theme.properties
├── admin
│ ├── messages
│ │ └── messages_en.properties
│ ├── resources
│ │ └── css
│ │ └── exadmin.css
│ └── theme.properties

Thanks!

Anyone has any tips/hints?

Wasn’t able to figure this out, guess it is not possible then?!
