+The Golden pack adds mechanics the Turtle pack doesn't have:
+
+- **Trumpets** — an ephemeral battle resource pets earn and spend mid-fight.
+- **Golden Retriever** — once per battle, a side that runs out of cards but
+  still holds Trumpets fields one, its power equal to those Trumpets.
+- **Avocado** — a persistent set-aside token you can discard in place of gold.
+- **Nurse Shark** — the one interactive battle moment: the fight pauses and
+  asks how many Trumpets to spend on rocks (the bot answers with a fixed
+  policy, so simulated rollouts stay valid).
+- **Cockatoo** — a shop-time reveal, plus Manta Ray's free first buy,
+  Blue-Ringed Octopus' per-buy apples, and more.
