/* CLIPZYN v7. THE TRANSMISSION.
   The photograph is the room; the CRT glass is live markup; the screen is the
   landing itself. Everything inside the glass speaks in old terminal type.
   Motion: scroll-scrubbed off the damped value, cursor-caused, or one-time
   load choreography. The block cursor blink is the one ambient voice, it is
   the carrier light of the terminal. Reduced motion renders complete, static. */
