The deck is parsed and drawn in this page: OPC/ZIP → PresentationML →
theme & layout inheritance → EVGDisplayList → WebGL 2.
The deck opens ready to edit: click a shape to pick it up, drag it, drag
a handle to resize, drag the handle above it to turn it, F2 to type in
it, Ctrl+Z to take it back. The panel on the left is the deck — click a
thumbnail to go there, drag one to reorder. Page Up and Page Down turn
the page (the arrows nudge whatever is selected), and the brush button
puts it back in read-only. Nothing is fetched while you
look. Open a deck of your own — it is read here, not uploaded.
