   Type:    Lexend for headings (built for reading fluency),
            Atkinson Hyperlegible Next for body (built for low-vision readers).
   Radius:  12px for containers and controls, 8px for anything nested inside one.
   Colour:  Blue from the flame logo for anything you can act on.
            Pencil yellow for emphasis only: highlights, badges, step numbers.
            Navy "board" for the interactive stage and the closing band.
