/* ---------- v1.1.0: AdEngine banner (adengine.us) ----------
   One labelled slot between the main content and the night footer, on the public pages only (the controllers opt in;
   never a drill, the practice card or a cheat sheet). The label (the eyebrow type: mono, --ink-3 on linen = 4.6:1), the
   reserved height and the space around it are all 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). The
   home page ends on the lighter band-alt, so the slot gets space above it there. display stays in this file and is never
   !important: tag.js hides a slot with style.display. */
