/* What each piece of an offer removes, and the steps either side of it.

   Three things share this sheet because they share one idea — an offer is judged
   on more than its price — and one set of tokens: the chip row that says which of
   three costs a composition addresses, the per-piece explanation under a bill,
   and the ladder of neighbouring products at the foot of a product page.

   Loaded wherever a composition card renders (product, family, catalogue, atlas,
   expertise and programme pages). Tokens only: nothing here names a colour. */

/* Tone per delivery primitive, so an explanation line wears the same colour as
   the letter in the bill above it. Declared here rather than borrowed from a page
   sheet: the expertise and programme pages load the ladder sheet, the catalogue
   loads the bundles sheet, and a line must not lose its colour on either. */
