   * Stone ramp. Each rung has ONE job, because the old ramp did not and the

   * Contrast against --ivory #F6F1E9 / --charcoal #22201D:
   *   stone      #443F39  9.27 ivory / 7.89 warm band   (body copy, ledes)
   *   stone-mid  #655E55  5.68 ivory / 4.84 warm / 6.03 panel  (hints, ordinals)
   *   stone-light #C6BFB4 8.91 on charcoal               (muted text on dark)
   *
   * stone-mid is scored against the WARM #E8DFD1 band as well as ivory, because
   * faint text lands on both. At #736C63 it cleared ivory at 4.61 and quietly
   * failed the band at 3.92 — passing on the surface you happen to test is not
   * the same as passing.
   *
   * These sit high on purpose. 4.96 and 6.37 both "passed" AA and both still
   * read as grey mush next to headings at 14.45 — passing the floor is not the
   * same as being legible. They stay well clear of 14.45 so headings and the
   * active nav item still outrank body copy; the ramp is compressed, not gone.
   *
   * The old file used --stone for body on light AND for muted text on dark
   * surfaces, where it measured 2.91 and failed AA outright. One value cannot
   * serve both directions; that is why stone-light exists and why stone must
   * never appear on a dark surface.

   * --brass is the brand colour and it is staying exactly as it is wherever it
   * is a rule, a border, a hairline or a fill — none of which carry a contrast
   * duty. But as TEXT or an ICON on ivory it measured 2.76, under both the 4.5
   * text floor and the 3.0 non-text floor. brass-deep is the same hue pushed
   * down in value until it clears both, on the warm #E8DFD1 band as well as
   * plain ivory, because brass text lands on both.
   *
   * Nothing on a dark surface changes: brass reads 5.24 there and is fine.
