Custom themes for opencode.
This option can either be:
- An attribute set defining themes
- A path to a directory containing multiple theme files
If an attribute set is used, the attribute name becomes the theme filename,
and the value is either:
- An attribute set that is converted to a JSON file (creates
opencode/themes/<name>.json)
- A path to a file (creates
opencode/themes/<name>.json)
If a path is used, it is expected to contain theme files.
The directory is symlinked to $XDG_CONFIG_HOME/opencode/themes/.
Set programs.opencode.tui.theme to enable the custom theme.
See https://opencode.ai/docs/themes/ for the documentation.
