IDIOT's duty spelled out, like FEAR's

The engine already steers every step and bars items, attacks, and
non-aiding casts; the one honor-bound piece is spending the movement at
all. The afflicted now see the card's demand in an urgent slip the
moment their turn opens, matching the FEAR pattern: bots comply
mechanically, humans get the words.
