 ## [Unreleased]
 
+### Fixed
+
+- Fixed `Container.render()` stack overflow on long sessions by replacing `Array.push(...spread)` with a loop-based push, preventing `RangeError: Maximum call stack size exceeded` when child output exceeds the V8 call stack argument limit ([#2651](https://github.com/badlogic/pi-mono/issues/2651))
