+### Simplified bank balance message

+| Component | Version | Affected source |
+| --- | --- | --- |
+| `tws_t5_bank.gsc` | `2.0.3` | `t5/scripts/tws_t5_bank.gsc` |

+- Both games now display `.b` as `Bank: {balance} points`, retaining the
+  existing colors and omitting the available amount. Update startup version
+  reporting and the existing balance-message fixtures. API data and point
+  accounting are unchanged.
+- Validation: all 42 portable bank script fixture groups passed with
+  `node tools/check_bank.mjs`, including exact balance text for both games.
+- Compatibility: no new dependency requirement; matching TWS plugins `1.2.0+`
+  remain required. Deployment: copy each updated bank script and restart the
+  map. No plugin update or full server-process restart is required for this
+  change. No deployment performed; GSC compilation and live T5/T6 display
+  verification remain required.
