/* Mobile (incl. Android): the desktop corner box doesn't work on a narrow,
   short viewport — it either overlaps quiz content or gets squeezed
   illegibly. Below 640px the avatar becomes a full-width bar pinned to the
   window's bottom edge, always painted above the page (z-index above
   .wrap's 41 — see index.html): the avatar block (.avatar-visual — the
   presenter plus its scene picker, stacked) on the left, and everything the
   learner reads/types ("communication": bubble/ask-form, .avatar-comm) on
   the right. The comm column scrolls internally so the bar never exceeds
   --avatar-bar-max-h; index.html pads .wrap's bottom by that same amount so
   page content and the toast never sit under it. */
