[Bug] ANSI light theme: question text renders in white, causing low contrast

Bug Description
When using gsd and answering questions in the ANSI light theme - the questions are white

I asked Claude to fix it and we changed my palette8 color - which works in the "light" theme but not the ANSI light theme.
