     The names keep the original ramp's numbering, but the text-bearing tints no
     longer match it: at their nominal alphas, --ink-40 through --ink-55 landed
     between 2.68:1 and 4.31:1 on --white, and every one of them is used on
     11–14px copy. They now sit just above the 4.5:1 floor (checked against
     --warm-white too, which is the darker of the two surfaces they appear on),
     which is why the four converge. --ink-08 … --ink-20 are hairlines and fills,
