/* ---------- v1.2.0: AdEngine banner (adengine.us) ----------
   One labelled slot between the main content and the chart title-block 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 and the space go with it (and the empty wrapper with :has). 110px = 16px label + 4px gap + 90px banner;
   270px on phones (300x250). The footer keeps its own 72px top margin and the pages end with their own padding, so the
   slot adds only a little space above; the home page ends on the tight "What this is not" box, so there it adds more.
   display stays in this file and is never !important: tag.js hides a slot with style.display='none'. Label: small caps in
   the body face (Saira's stretched caps split the word at 11px) in --ink2 (7.2:1 on the chart paper). */
