Anyone has experience with d2b?

Needs a comparison to its inspiration, @qyliss’s Spectrum project:

I’m not sure whether you’re asking for your own information or asking for it to have different documentation. In case it’s the former, it says that it’s a hobby project whereas Spectrum aims to be supported, and it has a smaller threat model.

Was looking for more technical detail than that abut how it differs implementation-wise.
Probably should have made issue with upstream to ask (no discussions enabled :frowning:) instead of asking here though.

Also,

Shared realm UI identity: d2b emits compositor-agnostic JSON and GTK-compatible CSS so niri, Waybar, wlcontrol, wlterm, clip-picker, and Wayland rails use the same host/realm/workload/state colors.

That’s rather cool.
