/* ==========================================================================
   Redemption page polish
   Loaded last, on the customer redemption page only. Visual layer only:
   no element, id, class or data attribute that app.js relies on is changed.

   Shape of the page
     - one 820px column, hero and card share the same edges
     - one card; the steps inside sit on a rail instead of in nested boxes
     - the CDK field keeps a complete border beside the recognised plan

   Colours come from the existing theme tokens (--ui-*), so the classic,
   black and white themes all keep working.
