# The vendor binaries were built against Qt 5 and ICU 73, neither of
# which Gentoo still ships; the matching runtime libraries are bundled
# from the same Fedora 39 release the vendor package targets.

# openssl and double-conversion are pinned to the subslots providing
# the sonames the bundled Qt 5 links (libssl.so.3, libdouble-conversion.so.3)
# so that an incompatible upgrade conflicts visibly instead of breaking
# the prebuilt binaries silently. The bundled Qt5Network also links
# libproxy.so.1, which current libproxy only provides as a compatibility
# symlink; re-check on bumps.
