   TWO-TIER ICON SYSTEM
   --------------------
   1. Line icons, inline SVG sprite at the top of each page, 'currentColor'.
      Used for UI: checkmarks, arrows, phone, mail, pin, social, the chat
      widget. They inherit color so they work on any background.
   2. Badge icons, individual files in assets/img/icons/, referenced with
      <img>. Full-color gradient illustrations used on feature and service
      cards. They cannot inherit color, so every one sits on a white disc
      (.badge). That disc is what makes the three different icon families
      (orange circle, green circle, cream tile) read as a single set, and it
      is what keeps them legible on orange, green and navy alike. Do not
      remove it.
