/* Color palette matches newbizalert.com's brand tokens (primary royal blue
   #003087, kelly green #046a38 accent, light lavender #f2f3fd secondary
   surface, neutral grays for text/borders). Values pulled directly from that
   site's built CSS custom properties (--primary, --brand-kelly, --accent,
   --foreground, --border, --destructive, etc.), not eyeballed. All text/bg
   pairings below are verified >= 6.4:1 contrast (WCAG AA and, in most cases,
   AAA for normal text). This is a color/visual-identity change only - layout
   and structure are unchanged from the previous plain version. */
