  /* Three colours, and colour is spent only on exceptions.

       Midnight Violet #160f29  text, and emphasis of every kind
       White           #fbfbfb  the page, and every surface on it
       Blue Slate      #5e6572  recessive: secondary text, and a non-match
       Copperwood      #bf6900  the only hue on screen, and only while
                                something is changing

     A matched tender is what the user came to see, so it is given weight — a
     solid ink fill — rather than a colour. A non-match recedes into grey. That
     leaves exactly one hue in the interface, and seeing it means something is
     in flight. A palette where the common case is coloured spends its loudest
     signal on the least surprising thing.

     Black Forest is gone. It was warm beside a cold ink, and at 12px it read as
     near-black rather than as green, so it was occupying a slot without
     delivering a signal. --accent now points at the ink, which is what carries
     emphasis everywhere: links, primary buttons, the eyebrow, the rule beside a
     reason that fits.

     Ink and ground are cold on purpose. The oxblood they replaced read as
     editorial — the register of a heritage brand rather than of an instrument,
     and this is a tool people scan under deadline. It is also measurably
     sharper: 17.9:1 against this white, where the oxblood managed 15.6:1
     against a warmer one.

     Everything else is derived from those so it follows them: the rule, the
     tint, the shadow, the scrim, the header. The exception is --warn-text,
     which exists because Copperwood measures 3.9:1 on this white and the badge
     label is 12px bold, under the 4.5:1 that size needs; the colour itself is
     unchanged everywhere it is not carrying small text. */
