InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
With regards to themes, it would be simpler to just set the dark theme in the Gnome Control Center, and then use something like adw-gtk3for the rest, so they all look like libadwaita.
BTW you mentioned extensions not working with Gnome 42, the extensions manager won't install them if they aren't, though. https://github.com/mjakeman/extension-manager
