My daily driver stack is Paseo + OpenCode + OpenViking. Paseo recently shipped an official plugin directory too, so now there's both the community one at paseo.cafe and the official one at paseo.sh/plugins. I'd ported the solarized theme earlier to go easier on my eyes, and it's listed in both directories.

I built a Solarized Light eye-friendly theme plugin for Paseo using the official addTheme plugin API. No need to touch any Paseo files, and nothing is lost on upgrade. Since Paseo 0.7.0 you can install plugins straight from GitHub, one command and you're done.
