/* ---------- v1.1.0: AdEngine banner (adengine.us) ----------
   One labelled slot between the main content and the footer, on the public pages only (the controllers opt in). The
   label and the reserved height are on the <ins>, so when tag.js (or ae-size.js) hides a slot it cannot fill, the label,
   the reserved space and the space below go with it. 110px = 16px label + 4px gap + 90px banner; 270px on phones
   (300x250). Every ad page ends with its own section padding, and the footer has no top margin, so the space below the
   slot sits on the <ins>. display stays in this file and is never !important: tag.js hides a slot with
   style.display='none'. */
