[Feature] implement dark mode theme to vocabulary site

[yashi-hub]

Problem

currently the vocabulary pages are just based out of 1 theme, i.e. white. A new theme can enhance the user experience signifantly.
to enable that theme, a vision button can be created on top right corner which allows the user to switch themes

it can look like

in dark mode. this image is just a rough idea to provide context.

Implementation

• I would be interested in implementing this feature.

This is well out of scope for the project at this time. It's not something we wouldn't revisit in the future, but it's not something that could be adequately addressed at this time given the degree of complexities of brand, color, accessibility, usability, and color organization that would need to be addressed.

However, given that we might revisit it in the future I'll move this to 🚧 status: blocked Blocked & therefore, not ready for work for now.
