This seems very worthwhile, good on you for forking and resurrecting this.
It might be worth you updating the about page to say what lightly is - I had to google and find the original git to work it out. I'm still not even entirely clear - this seems to be more than a theme? As well as retheme Breeze It also seems to expand on what Breeze does?
Your project can stand on its own merits rather than just referencing defunct projects - that might help future new contributors better understand what the ask is and get then more interested / excited about helping?
I don't think hyperbole like damage lasting for millenia is worth much. People don't think in such terms and the only people who will listen to that are those who are already on the side of climate action.
The articles call to arms is right, but this is not the way to beat trump. Instead of damage for millenia, the focus needs to be on convincing people that his short termist policies will damage then financially and personally.
Instead of cheap renewable electricity he wants to use voters tax money to subsidies and promote fossil fuels. Instead of clean cars in cities and towns, he wants to choke you and your children with petrol fumes.
An image of trump in a jacket covered in fossil fuel company sponsorship logos, and trying to force an exhaust pipe down a child's throat is the kind of thing that summarises his position. We're not trying to convince die hard republicans, just the moderate centre / undecideds that trump will harm them and their children directly with his policies, let alone millenia of damage.
