/* Retail-mandate traceability wedge pages.
 *
 * Palette, type stack and component shapes are lifted from the canonical
 * marketing surface, greenreach-central/public/purchase.html — tokens at its
 * :root (lines ~31-41), nav (~1090-1110), hero/button rules (~140-215) and
 * footer rules (~781-850). purchase.html keeps its styles inline; these five
 * sibling pages share one sheet instead of carrying five copies of it.
 *
 * Light palette, matching purchase.html. Deliberately no dark-mode block: the
 * marketing surface commits to one look and a half-converted page would read as
 * a different site mid-funnel.
