/* Planora home page. Builds on the tokens and components in styles.css (sheet, quick, task-row,
   ribbon, flaps, hbars, seg) so the tour looks exactly like the app it is showing.

   Motion has one voice: things land like a stamp on paper. They drop a few pixels with a slight
   overshoot and their hard shadow appears under them. Loops (the day ribbon, ticker, focus timer)
   pause when off screen, and none of them run with reduced motion. */
