   Case studies: the story card slides out from behind a phone that plays
   the client's ads as Instagram-style feed posts (js/stories.js). The phone
   and feed post are a port of ms-web /work's mock-up: the frame scales from
   /work's 651px-tall phone (--u = 1/341.54 of the frame width), and each
   post is drawn at a 390-wide logical screen scaled to fit (--s).
