 ### Fixed
 
+- Fixed HTML export losing indentation in ANSI-rendered tool output (e.g. JSON code blocks in custom tool results) ([#1269](https://github.com/badlogic/pi-mono/pull/1269) by [@aliou](https://github.com/aliou))
 - Fixed images being silently dropped when `prompt()` is called with both `images` and `streamingBehavior` during streaming. `steer()`, `followUp()`, and the corresponding RPC commands now accept optional images. ([#1271](https://github.com/badlogic/pi-mono/pull/1271) by [@aliou](https://github.com/aliou))
