/* ------------------------------------------------------------------
   Article formatting pilot — presentation components (v2).
   Scoped to `.fmt` (added on the article body wrapper) so nothing here
   touches live articles. Colors are the site's existing tokens; the only
   additions are an amber tint (warnings, caps) and a green tint
   (eligibility, success) used inside callouts and checklist markers.
   v2: every block is a real card (tinted fill + rounded border), data
   tables live inside cards instead of drawing their own grid, callouts
   carry an unmistakable state color, and sections are separated by rules.
