Removing the eight-second teaser left this page with nothing at all, and the
replacement had been rendered and published hours earlier without ever being
wired in.
Twenty-seven seconds of a live deck: fragments arriving one key-press at a time,
a hotspot jumping to a branch slide, the back control returning to the exact
fragment it left, and presenter mode with real notes and a running timer. It is a
capture of the deck running, not a video of slides.
Guides with nothing to look at: 5.
