   Stylesheet for the Brochure & Specifications page

   Deliberately independent from aircraft-details.css (the
   cost-calculator page's stylesheet) — the two pages must not
   share a file, so editing one can never affect the other.
   The base design system below (nav/hero/specs-grid/faq/related/
   footer/responsive) is intentionally the same visual language as
   aircraft-details.css, duplicated here on purpose.
