It is now the same as in my site. I found it to be surprisingly useful
but it needs a little widget like a button to make it fullscreen to make
it more accessible especially at larger screens.
The Hugo theme will also generate a counterpart system theme if there's
only one system theme given. Though, it isn't perfect so the release
will not happen for a while. I'll look into generating a color palette
with HSLuv to see if it can be improved.
I've also put more comments on the individual components in the partial.
Hopefully, that'll mitigate against me forgetting their purpose all over
again.
It should be easier to integrate it with other libraries such as Prism,
Mermaid, and D3 especially in the graphics department where it mostly
use vector graphics to do its thing.
