Codex chat font size is too small in the VS Code extension

What version of the IDE extension are you using?

26.318.11754

What subscription do you have?

Plus

Which IDE are you using?

VS Code

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What issue are you seeing?

The font size in the Codex chat panel is too small for comfortable day-to-day use.

It is noticeably smaller than the default font size used in the code editor. I understand that it may match the general VS Code sidebar UI, but I do not think that is a good baseline for a chat panel, because users read much more text there for long periods of time.

I have normal vision, but the current font size causes eye strain during longer Codex sessions.

For reference, I attached a screenshot comparing the default editor font size with the Codex panel on the right.

Font size in the chat should either be slightly larger by default, or there should be a user setting to adjust it.

What steps can reproduce the bug?

1. Open VS Code with the Codex extension installed.
2. Open the Codex chat panel.
3. Compare the text size in the Codex chat panel with the default text size in the code editor.
4. Read a longer conversation in the Codex panel.

Result: the text in the Codex chat panel appears too small and is uncomfortable to read for longer sessions.

What is the expected behavior?

The chat text should be easier to read.

Ideally, the default font size in the Codex chat panel should be a bit larger, closer to a comfortable reading size, or there should be a setting that lets users adjust the chat font size.
