   --g-gloss  English glosses and secondary text that carries meaning (≥ 5:1). --sub is for decoration, disabled
              things and placeholders only: it is about 2:1 on most themes, unreadable as text.
   --g-edge   visible edge of inputs and outlined controls (≥ 3:1).
   --g-coin-ink / --g-ok-ink   coin gold and "correct" green as TEXT (≥ 4.7:1): the lightness moves towards
              --text (dark gold / green on light themes, bright on dark ones), hue and chroma stay. Keep --g-coin and
              --g-ok for fills, bars, borders and icons. Browsers without relative colours fall back to the
