/*
  Styles for the QB Gen part of the page design.html

  IMPORTANT: Do not use CSS custom properties (var(--token)) in @media queries.
  Browsers do not evaluate variables inside media feature ranges, so rules like
    @media (min-width: 640px) { ... }
  will never apply. This caused sections (e.g., top bar and deliverables) to remain
  single-column at all sizes.

  Policy going forward:
  - Use hard-coded pixel breakpoints in media queries (e.g., 640px, 768px, 960px, 1024px, 1280px).
  - Keep tokens for colors/spacing/etc. inside rule bodies, not in @media conditions.
  - Where possible, prefer layout primitives (CSS Grid/Flex) that degrade gracefully.

  Example used below for deliverables:
    .df-grid-two { display:grid; grid-template-columns:1fr; }
    @media (min-width: 640px) { .df-grid-two { grid-template-columns:1fr 1fr; } }
