# UI is effectively a clone of Fractal.
# compatibility:
# - desko: works fine. pairs, and exchanges contact list (but not message history) with the paired device. exchanges future messages fine.
# - moby (cross compiled): nope. it pairs, but can only *receive* messages and never *send* them.
# - moby (cross compiled flare-signal-nixified): nope. it pairs, but can only *receive* messages and never *send* them.
# - even `rsync`ing the data and keyrings from desko -> moby, still fails in that same manner.
# - console shows error messages. quite possibly an endianness mismatch somewhere
# - moby (partially-emulated flare-signal): works! pairs and can send/receive messages, same as desko.
