/* WhiteBridge "Install app" prompt.

   Two rules drive every decision here:

   1. It has to read as an APP install in the first half-second. That means the
      native smart-app-banner idiom people already know from iOS and Android —
      a squircle app tile, the app's name, a "Free" meta line and a GET-style
      pill — plus, on the roomier placements, a literal picture of the icon
      sitting on a phone home screen.
   2. It has to be WhiteBridge, not a generic card. Tokens are lifted from
      public/css/app.css: #EAECF0 hairlines, 16px card radius, 8px control
      radius, #2337E0 / #1A2BC8, #101828 ink, #475467 / #667085 muted. */
