FR-DSP-8 asks for a fallback that is *defined*, and a reason that
reaches the code but never the screen satisfies half of it. The three
readouts are now built by a free function over the survey rather than
written straight into the window, so a test can assert that "sRGB
assumed" arrives with the reason attached, that an approximated profile
says "nearest to" rather than claiming the space, and that the second
monitor is described on the page read from the first — which is the
display the requirement is actually about.
