/* ---------- v1.1.0: AdEngine banner (adengine.us) ----------
   One labelled slot between the main content and the footer, on 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 and the space
   go with it. 110px = 16px label + 4px gap + 90px banner; 270px on phones (300x250). Some pages end on a lilac band, so the
   slot keeps white space above and below; the label is set like the eyebrows (mono caps) in the muted ink. display stays in
   this file and is never !important: tag.js hides a slot with style.display='none'. */
