  /* Brand colors
     #F78220 is the only corporate orange. On white it is 2.57:1, so it is a fill
     and emphasis color, not small text and not white-on-orange text.
     --color-accent-dark is the button hover fill (brand mixed 15% toward black).
     Navy text on that fill is 5.17:1. It is an interactive state, not a second brand orange.
     --color-accent-ink is the same hue mixed 35% toward black, for text, borders,
     and focus on light surfaces (5.53:1 on white). */
