One original constraint card in the tradition of lateral-thinking decks: a short instruction, reversal or question you can apply to whatever is stuck, written fresh by a model at high temperature on every call. The cards are ours, never a card from any published deck. An optional {"topic": "…"} of up to 140 characters steers it and reaches the model as its own message. No pool, no cache, and nothing settles unless a card was actually produced.
