       #8B9A6E olive   #F7F2EB cream   #EAE2D6 sand   #EEEEEE paper

     Sand is the ground and cream the raised surface — the palette's own two
     warm tones, in the order that makes cards read as lifted. That is a 1.15:1
     value step, so a card no longer depends on hue alone to separate from the
     page. #EEEEEE is deliberately unused: a flat grey with no hue at all, sat
     next to a distinctly warm cream, put a temperature seam down the page.

     Chips, the icon tiles and the hero wash are tinted toward the olive rather
     than the sand, which is what gives the accent any presence — it is the
     only chromatic colour here, and confined to a button it read as garnish.

     Ink is derived: none of the four swatches can carry body text. */
