Placing a card locked the turn in: the chosen card left the hand and no
affordance reverted the placement, forcing the move through. Clicking the
chosen destination again or pressing Escape now steps the selection back.
A failing ONNX inference left the AI's turn unadvanced, permanently
stalling the game. The AI turn now falls back to the heuristic policy.
Other fixes: the score plaque no longer covers hand cards (plaques become
compact chips at narrow widths and hand spacing tracks the viewport),
opponent cards drawn from a discard pile render face up, long expedition
stacks stay inside their lane, undo no longer bumps the generation counter
on empty history, and small viewports scroll instead of clipping.
