Edge cards light their targets; own casts never wrench the neck

Raising an edge-target card now makes every wall and door face
breathe faint gold in the pane — the cockpit's answer to the board's
edge handles — with hover still brightening the chosen face. And the
director's own-magic aim gains a quarter-turn cap: a deed you aimed
behind you via the keymap stays behind you, while deeds done TO you
may still spin the world.
