What version of Codex is running?

codex-cli 0.3.0

Which model were you using?

codex-mini-latest

What platform is your computer?

Darwin 24.4.0 x86_64 i386

What steps can reproduce the bug?

When I get an explanation from codex, sometimes it includes markdown code snippets, it would be great if this are syntax highlighted in the way that Github Copilot Chat does, or in any way really, it would make it easier to read.

What is the expected behavior?

Syntax highlighted code

What do you see instead?

│```ts                                                                     ││
│if (typeof outputDef === "string") {                                      ││
│  return port === "value" ? outputDef : null;                             ││
│}                                                                         ││
│```  

Additional information

Using VSCode with zsh. Maybe I can use codex-mini-latest with Github Copilot Chat in agentic mode? Will that be as good?

See https://github.com/openai/codex/issues/1246

Note that tagged code blocks do seem to get highlighted for me in some cases, but I don't know how broad the language support is for syntax highlighting in the library we are using offhand.
