uninitialized constant Spina::Theme::OpenStruct with Spina 2.18.0 and Rails 7.2.2 on Ruby 3.2.6

after logging in /admin/login

uninitialized constant Spina::Theme::OpenStruct

continues to happen downgrading to Rails 7.1.0

could also just be a scope of that module name issue maybe prepend with ::OpenStruct.new({ ...

I added ostruct to my gemfile and I still get the error.

Might be related to Ruby Ostruct being pulled out of system gems though. I didn't see evidence of that with Ruby 3.2.6 but Ruby 3.5.0

I was able to get this working without changing that file with:
Ruby 3.2.6
Ruby on Rails 6.1.7.10
Spina 2.18.0
Graphicsmagick 1.0.6

The ROR version being the important part, the rest for reference only.

I've just added a require 'ostruct'. Should work in any place. I've just added it on top of the Spina initializer.
