   Palette: #00FFFF cyan accent | #2E4057 deep slate base
            #4DB6AC teal support  | #FA8072 salmon highlight
   Design tone: geometric headings + neutral body, light card rounding,
   compact buttons, image cards with bottom name bars, question-driven
   rhythm, color-only state changes, short vertical lift on the dock.
