     Was #00D4AA / #00B899 / #00EFC2 — all three at 100% saturation, which is
     what made the accent read as poster paint rather than as a brand colour.
     Nothing in a considered palette runs at 100% S. Same hue family (168-172),
     pulled back to 78-80% and deepened, so it stays recognisably SkyKaro while
     behaving like ink.
     Side effect worth keeping: --sk-teal-dark now clears AA as text on white
     (4.9:1, was 2.5:1), so the badge and label type that uses it is legible. */

     overnight pill all fell through to a raw #F59E0B: 92% saturation, and
     2.15:1 as text on white. A second, different amber (#D97706, 3.19:1) was
     used for the same meaning on the checkout itinerary.

     The page is NOT white and the cards ARE. That ~2% luminance step is what
     lets the shadows stay near-invisible; both reference sites do it, and it
     is the reason their cards read as objects without heavy borders.
     Every neutral here is pulled into the indigo family of --sk-primary

     anywhere. That single choice does more work than any shadow. */

     There used to be no ladder in practice: buttons came in 8, 10, 12 and

     system. The rule now:
       sm  10px  small controls — chips, icon tiles, menu items
       md  14px  inner tiles inside a card
       lg  18px  medium panels — dropdowns, popovers, notices
       xl  24px  EVERY card. One card radius, no exceptions.
       2xl       kept as an alias of xl so the ~26 existing call sites do not
                 all have to be rewritten, and so a 32px card cannot creep
                 back in by using the old name.
