## —— Profiling build (dial9 Tokio runtime telemetry) ------------------------------------------

# dial9 hooks Tokio's unstable runtime instrumentation, so it needs
# `--cfg tokio_unstable`. That flag is deliberately absent from
# .cargo/config.toml: it is not free, and release binaries do not carry it.
# Setting RUSTFLAGS here replaces (never appends to) the config-file value, and
# crates/obs/build.rs fails the build if the feature and the flag disagree.
#
# DIAL9_FEATURES can add `dial9-taskdump` (async backtraces of stalled tasks;
# Linux x86_64/aarch64, and also needs --cfg tokio_taskdump). There is no S3
# upload feature — see the note in crates/obs/Cargo.toml.
