Stage 6 (part 2): rest of the client app in the new style, promo code in the order form

Profile with club card, plum theme for buttons/selections and the sticky total,
move screens with the full-width hero, services/docs headers, empty docs fix.
Promo code field: applies to the quote, shows why a code is rejected,
says when the membership discount is bigger.
