# The SHIPPED name is `qbz` (owner, 2026-08-04). The package stays
# `qbz-qt`, so `cargo build -p qbz-qt` is unchanged; only the artifact
# moves to target/<profile>/qbz.
#
# ⚠ `crates/qbz` (the Slint binary) declares the SAME bin name and
# shares this workspace's target dir, so both write
# target/<profile>/qbz and the last build wins. That is survivable only
# because the Slint binary is never built in this worktree (the qbz-ui
# 20-30 GB wall). If it ever is, whoever built last owns the file — and
# a smoke against "the wrong qbz" is silent.

# The comment below is copied verbatim from the reference

# zbus 5 executor to tokio graph-wide (breaks accesskit/atspi plain-thread
# connections — see the rfd comment above). We only use the blocking API on
# worker threads; async-io self-drives the connection from any context.
#
# ksni 0.3.4 is already in the workspace lock (pulled by crates/qbz), so this
# adds no new lock entry. Feature unification is per-crate-graph, not
# per-target: ANY dependency that turns on zbus/tokio poisons the whole binary.
