> 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.
