/* Counter Intelligence web app -- house style (docs/UI_STYLE_GUIDE.md draft):
   iOS grouped background (#F2F2F7), white cards with a 16px radius, Title
   Case labels, one font family (Inter, bundled below -- the page's
   Content-Security-Policy allows no outside hosts, so the file is served by
   this app itself, with its SIL OFL licence beside it at
   /static/INTER-LICENSE.txt).

   Accessibility floor (UI council, 2026-09-24): every control is at least
   44px tall, inputs are 16px (so iPhone Safari never zooms in), input
   borders and the focus ring are at least 3:1 against white, and nothing
   may scroll sideways at a 390px phone width. */
