   timing verdicts in four hues could not clear the all-pairs colour-blindness
   floor on a dark surface (worst pair measured at delta-E 1.6), so identity is
   carried by a written row label everywhere instead. Do not add a series

/* "Never asked for" is not "asked for and rarely hit" (D, fix pass 3). The
   ramp is inverted -- a rarely-hit position is the PALEST blue -- and a
   never-asked square used to be a faint blue-grey wash, which put the two
   nearly side by side in lightness. An outlined, unfilled square is a
   different KIND of mark rather than a lighter one: it reads as absence at any
   size and it survives greyscale and every colour-vision deficiency. */
