/* /css/signup.css
   Version: 3 (2026-10-20) css-style-system names: colours, font sizes and corners use site.css's :root names at
   the same values (13 colours, 8 sizes, 3 corners), and the 8 var() fallbacks are gone (each name is defined, so
   none ever applied). No visible change.
   Version: 2 (2026-10-12) compact fields (Steve): .su-narrow caps the Fleet
   name field (24 chars) so it no longer stretches the full line.
   Version: 1 (2026-10-12) billing-company redesign piece #3: the five-step
   sign-up accordion on /signup.asp. Loaded by that page only, after site.css,
   so the shared stylesheet is untouched. Reuses site.css tokens
   (--navy, --gold, --ink, --muted, --line, --ivory) and the .signup-page,
   .signup-card, .signup-price, .signup-terms and .signup-msg rules. */
