/* ---------- 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 bottom padding on the paper background, so the slot needs space only below it, before
   the dark footer, kept on the <ins>. display stays in this file and is never !important: tag.js hides a slot with
   style.display='none'. */
