# Runtime deps reflect what the bundled JDK actually links against
# (libawt_xawt.so → libX11/Xext/Xi/Xrender/Xtst; libjsound.so → libasound).
# JRE of the system is NOT used: bin/Bisq2 is a jpackage native launcher
# that uses the embedded runtime in /opt/bisq2/lib/runtime/.
# net-vpn/tor is NOT needed: Bisq 2 downloads its own Tor binary at runtime
# into ~/.local/share/Bisq2/ via TorInstaller/TorBinaryZipExtractor.
