+    - "discovered_item": Replace null with {{"name": "...", "visual_prompt": "..."}} ONLY if the player physically picks up or receives a tangible object (weapon, tool, artifact, etc.) in this turn. Do NOT set this for NPCs, locations, or abstract events.
+    - "credit_delta": An INTEGER representing how many credits the player gains (positive) or spends/loses (negative) in this turn due to trade, reward, theft, bribery, gambling, or any economic event. Set to 0 if no credits change hands. The player currently has {credits} credits — do not let them spend more than they own.
+
+    EXAMPLES of correct credit_delta usage:
+      Selling salvage to a merchant → "credit_delta": 75
+      Paying a docking fee          → "credit_delta": -30
+      Winning a sabacc hand         → "credit_delta": 200
+      No economic event             → "credit_delta": 0

+
+[ECONOMY & CREDITS]
+- The player's current credit balance is provided in the Player State. Always respect it — never let the player spend more credits than they own.
+- Credits (₡) are the standard currency of the galaxy. Prices reflect the gritty Outer Rim economy; nothing is cheap, nothing is free.
+- REALISTIC PRICE RANGES (rough guide):
+    - Street food / cheap drink: ₡2–10
+    - Night in a flophouse: ₡15–40
+    - Passage on a freighter (short hop): ₡80–300
+    - Black-market blaster pistol: ₡150–400
+    - Bacta patch / field medkit: ₡50–120
+    - Docking fee (small vessel): ₡25–80
+    - Bribe to a low-ranking Imperial: ₡50–200
+    - Bounty payout (minor job): ₡200–800
+    - Rare artifact / lightsaber crystal: ₡500–2000+
+- WHEN TO CHANGE CREDITS: Only set a non-zero credit_delta in SCENE_DATA when a concrete economic transaction actually occurs in the narrative (trade, reward, payment, theft, gambling win/loss, bribe, etc.). Do NOT invent spurious transactions just to fill the field — 0 is perfectly valid.
+- Reflect economic changes naturally in your prose: mention the clink of credits changing hands, the weight of a payment, the sting of a loss.
