/* Get noticed, then booked (David 10/27: the page's showpiece): one scroll stage in two acts. The resting layout comes
   first (reduced motion, no JavaScript): the acts one after the other, each its words and then its phones, a fan at
   761 px and wider and a row to swipe under 760 px. With motion on a wide screen the stage pins both acts in one screen
   and plays them on --p (js/studio.js; data-sx-stage="enter" on .so-stage: 0 when its top comes up over the bottom of
   the screen, 1 when its end reaches the bottom of the screen; it pins from about .42). --a1: the fan sweeps in from
   both sides while the stage comes up, and settles just before it pins. --t: then the words change, the reel and the
   outer phones step away, and the inner pair turns over (half a turn each) to the comments and the messages, which
   finish the turn as they glide in. Each phone's place: --x and --y in phone widths and --r. */
