   17. MOTION
   Inventory, with the reason each one exists:
   a) .salient reveal   : a long dark page arrives in readable pieces rather
                        than all at once, which keeps the eye moving down one
                        column instead of scanning for an entry point.
   b) .survey--sunk : the bar gains an opaque backing once it leaves the
                        photograph, so the links never sit on moving imagery.
   c) cubby slide     : the drawer enters from the edge it will return to, so
                        its origin and exit are obvious without a label.
   d) traverse lift     : on a dark surface a colour shift alone is easy to
                        miss, so actions also move 2px on hover.
   Everything above is cancelled under prefers-reduced-motion.
