/* ============================================================
   "Real calls, real judgment" section  ·  css/use-cases.css

   Each case is a row: explanatory TITLE + DESCRIPTION on one side, and
   a DESKTOP SCENE on the other — the user's screen with an Askpilot
   popup that pops over it (exactly like the How It Works Step 2 "On a
   call" / approvals window). The desktop, menubar, wireframe browser,
   dock and popup chrome all reuse the .hiw-* classes from
   css/how-it-works.css; this file only sizes things for the column and
   styles the popup's inner content (message, options, approve, confirm).
   js/use-cases.js pops the window in, dims the desktop, then plays the
   human response (select an option / press Approve) + a confirm line.
