# Important decision: separate `bench` profile uses fat LTO for the most
# aggressive cross-crate inlining. Criterion benches run rarely and we'd
# rather spend extra compile time once than miss inlining opportunities
# across the interpreter / parser / builtins boundary on every measurement.
# `release` keeps `thin` LTO so day-to-day builds stay fast.
