/* The picture frame screen (module frame): /screen/frame/ on an old iPad, a tablet or a TV browser, and /tv/frame on
   an in room TV. Full screen photos on black with a crossfade, a large clock and date that read from across a room,
   the caption and who sent it, and "New photo from Nina" for a minute when one arrives. Sizes follow the screen
   (vmin), so a 1366x1024 iPad and a 1920x1080 TV look alike. Written for old browsers too (iOS 9 Safari, webOS 3):
   flexbox and absolute positioning only, no grid, no gap, no inset, prefixed transforms and filters. Brand colors
   come from the client's tokens (partials/theme). */
