/* Homepage: one meeting, followed from the call to the disk.
   The page is a scroll story in four pinned scenes. A fixed "world" layer
   behind everything changes colour as the story moves through night (the
   call), forest (your own processor), paper (the transcript), a note-yellow
   desk, daylight, and dusk (the years after one payment).

   The two source colours carry meaning everywhere: violet is your
   microphone, teal is the meeting audio, as in the desktop app. Nothing else
   uses them.

   Under html.motion (set by /js/motion.js before first paint) the scenes pin
   and animate. Without JavaScript, or with reduced motion requested, the
   same markup renders as ordinary stacked sections with their own colours. */
