   quote-layout.css — CNCQuoter quote page · LAYOUT & STRUCTURE
   Companion to quote.css (which covers step nums, mono, DFM status,
   preview controls, ETA, share toast, skeleton, dark-mode tokens).

   This sheet handles the structural classes the prior quote.css didn't
   cover: nav, page header, two-column main grid, cards, form sections,
   delivery rows, actions, trust strip, DFM detail panel, info+FAQ,
   case grid, minimal footer.

   Design tokens come from tokens.css; everything here follows the
   same yellow-accent / light-gray-bg / white-card system as landing.
