{{--
    Where you are in the four steps.

    Steps already passed are links back, so a wrong patient can be corrected
    without abandoning the tests already chosen — the draft survives, and
    stepping back is the cheap way to fix a mistake rather than starting over.
    Steps ahead are not links: they need the answers this one is asking for.
