/* ── .cx-flow — the compliance evidence-trail figure ────────────────
   Used by Views/Shared/_ComplianceFlow.cshtml on the Compliance page
   (full container width, three stages across) and on the home page
   (two-thirds column, stacked). It sizes itself from its CONTAINER,
   not the viewport, which is what lets one component serve both:
   a viewport media query would read "desktop" and lay three cards
   across a 736px column.

   The media query below repeats the stacked rules as a fallback for
   browsers without container queries — there a phone still stacks,
   and only the home page's desktop column stays wide. */
