Huh, and here I was thinking it was written as 'lunapunk'!
Lunarpunk
Lunarpunk is a subgenre of solarpunk with a darker aesthetic. It portrays the nightlife, spirituality, and more introspective side of solarpunk utopias. It can be defined as "Witchy Solarpunk." Aesthetically, lunarpunk usually is presented with pinks, purples, blues, black, and silver with an almost omnipresence of bioluminescent plants and especially mushrooms

Solarpunk Station - What is Lunarpunk?
What is lunarpunk? - Solarpunk Druid
I guess that would make sense too as “luna” and “lunar” both have to do with the moon
I think "luna" sounds a bit more dreamy, which is what I associate with the lunarpunk vibe, maybe that's why. But compare with solarpunk (and not solapunk or something), it makes sense!
