 let-go stays compact and quick to launch: a small native binary, fastest startup
 in this run, low RSS, and no JVM dependency.
 
-On runtime benchmarks, let-go is competitive on short-lived data work like
-map/filter (7.2ms) and persistent maps (20.2ms), and it is still much faster
-than upstream Joker on numeric/tree-walk-heavy cases. go-joker's WASM JIT leads
-hot loops and reduction/transducer workloads; Babashka is ahead on several
-algorithmic cases; and the JVM dominates long compute runs once HotSpot warms
-up.
+On runtime benchmarks, the VM is competitive on short-lived data work —
