[keycloak-user] Extending Themes via SPI

[Stian Thorgersen]

I strongly recommend against going down the JSP route, and we do not have
time to provide you with help on doing so. You have nothing to gain, only a
lot of work and headaches.

That being said the SPI is there and you can rip out our FreeMarker
implementation if you so please. As it's a SPI you do not need to modify
Keycloak source code, instead you create your own provider implementation
of the SPI. Take a look at the providers section of the documentation for
more information.

Most likely you won't even need to touch the FreeMarker templates and you
can acommodate the changes you need purely with stylesheets.
