   * Brand greens (29 Oct 2026: Lionel asked for a brighter green throughout).
   * --green is now the business-card green (#43c25a) and is the site's main
   *   green: buttons, icon tiles, rules, dots, borders, underlines, the
   *   header/footer accents and links/focus rings on dark backgrounds.
   *   It is too light for white text (2.31:1), so anything sitting on it uses
   *   --on-green (#0a0a0a): 8.58:1. On dark bands it is 9.10:1 on black and
   *   7.74:1 on navy.
   * --green-hover (#5ccf71) is the lighter hover shade for green buttons
   *   (10.01:1 with --on-green).
   * --green-text (#2a833a) is the same card hue darkened just enough for small
   *   green text and focus rings on light surfaces: 4.77:1 on white, 4.56:1 on
   *   --gray-100. #43c25a itself is only 2.31:1 on white, so it is never used
   *   for text on light backgrounds.
   * --green-text-large (#36a94c) is for large display text on white only
   *   (the hero headline): 3.03:1, which meets AA for large text (3:1).
   * --green-text-hover (#22682e) is the hover shade for green text links
   *   (6.80:1 on white).
