   NEUTRALIZE THEME CARD/WRAPPER
   Scoped to .acfb-single-wrapper so only this template is affected.

   The theme applies white card styling through multiple CSS files:
     - style.css: #main { background: #fff; border; padding: 30px; margin; border-radius }
     - style.css: #wrapper { margin: 20px auto 40px auto }
     - style.css: #leftWrapper { float: left; width: calc(100% - 350px) }
     - responsive.css: #main { width: calc(100% - 20px); margin }
     - top-banner-wide.css: main article { max-width: calc(100% - 20px) !important }

   We use !important to override all of these reliably.
