This issue might be a duplicate of existing issues. Please check:

• Auto theme mode does not work in tmux popup #19254: Auto theme mode does not work in tmux popup — similar report of system/auto theme not being respected, though specific to tmux popups
• TUI: system theme not found on macOS #10661: TUI: system theme not found on macOS — related issue about system theme detection on macOS

If your issue is distinct from these (e.g. it previously worked and recently regressed specifically with Ghostty), please add that context to help distinguish it.

This is not related to tmux or the opencode system theme

I have the opposite problem, opencode keep using dark variant even though everything else on my machine using light variant (OSX + kitty)

I'm experiencing this issue in both Windows & MacOS in default terminals.
While using "one-dark" opencode 1.4.7 using dark mode every time, opencode 1.4.0(i downgraded it) uses light mode in light dark mode in dark etc.

So this is a new issue i hope its fixed.

Version 1.4.8 also broke the "system" theme.
