/* /membership and its wizard steps (review, account, checkout, success) — restyled to match
   the established Vox design system already applied to home/cities/newsletters/sponsorships.
   There is no brand-exploration prototype file for this flow, so this is not a port of a
   specific file: tokens, button, and card treatments are copied from the SAME real values used
   everywhere else (see sponsorship_front.css's .so-front block and
   docs/product-knowledge/tokens/tokens.css) rather than invented. Scoped under .mf-front so it
   never leaks onto other pages. Uses the shared Vox masthead/footer (@suppress_site_header is
   set true by the controller for every action here), matching home/cities/newsletters. */
