>
> In the embedded
> shell panel \(camel\-jbang TUI, ShellPanel\), text echoed while typing a
> command, and error output such as "Unknown command: x", render in a dark red
> \(\~RGB 136,0,0\) that is hard
> to read on dark terminal themes. The prompt itself renders fine \(camel in
> orange, version in green, > in white\).
> Root cause: JLine command highlighting colors unrecognized
> commands with ANSI red \(index 1\), and JLine ScreenTerminal encodes named
> ANSI colors as a 4\-bit\-per\-channel RGB value.
> ShellPanel.convertAttrToStyle reconstructs that as a
> literal dim RGB instead of a terminal\-themed named color. Elsewhere
> \(TuiHelper\) the TUI uses Color.ansi\(AnsiColor.RED\) so the host terminal
> applies its theme and stays
> readable.
> Acceptance: command echo and shell error output are legible on dark and light
> terminal themes, consistent with how other TUI components render ANSI
> colors.
