/* =========================================================================
   dual.fit/new/convert — ONLY what this page adds on top of v3.

   The page links /marketing/v3/styles.css first and is built from v3's own
   components: .nav, .btn (--light / --outline), .hero__title / .hero__sub,
   .hcard (the glass product cards), .sec / .sec__head / .sec__h, the .rail
   of .rcard numbered cards, .dev (the Figma handset) and the .footer close
   with the giant wordmark. Anything restyled here is because a converter
   recording needs it, not to make a second visual language. Brian
   (2026-10-12): it must look like v3's custom elements, not a generic page.
