/* ============================================================
   California DMV — Calm Prototype
   Static HTML/CSS only. Inter + Material Icons.

   DESIGN DECISIONS (tldr)
   -----------------------
   • 16pt body = 21.333px → --font-body. Headings scale up from there.
   • 14pt buttons = 18.667px → physically large via generous padding.
   • Navigation blue matched to the supplied DMV logo background:
       --blue-900 #187EC7   (nav background, sampled from logo)
       --blue-700 #2B4FA0   (primary buttons, links)
       --blue-600 #3B62B5   (hover)
       --blue-100 #E8ECF4   (filled icon backgrounds)
   • Light-blue surfaces replaced with calm greys:
       --surface     #FFFFFF (cards)
       --bg          #F7F8FA (page)
       --surface-2   #F2F4F7 (subtle fills)
       --border      #E3E5EA (soft hairline)
   • Section gap: 96px. Card gap: 24px. Generous padding inside cards.
   • One outline style: 1px solid --border. No competing card outlines.
