 ### Loop Index in Local
 
 **Status: Done.** DO/LOOP index and limit are kept in WASM locals. Two codegen paths:
+
 - **Fast path** (body has no calls, no `>R`/`R>`): pure locals, zero return stack traffic. `I` reads from `local.get`. `J` also reads from outer loop's local.
 - **Slow path** (body has calls or explicit RS ops): locals used for loop control but synced to return stack for LEAVE/UNLOOP compatibility.
