         "tentative" is not a warning and "free" is not a success — so these are their own tokens instead
         of being bent into --ok/--warn. Hue is fixed per state and only lightness differs by theme.
         Light values clear 4:1 on --panel, comfortably over the 3:1 a non-text indicator needs; the old
         hardcoded values turned out to BE the dark values in three of four cases, which is what the
         audit meant by "chosen for a dark ground". Measured light: 4.16 / 4.08 / 4.53 / 4.09. */
