State Safety & Action Creator Guard

Ensure global state remains consistent, immutable, and valid.

Workflow

1. Use Action Creators

   • Rule: Never dispatch raw objects (dispatch({ type: 'FOO' })).
   • Fix: Import from src/context/actionCreators.js.
   • Cross-check: Verify reducer handling in gameReducer.js.
   • Why: Centralizes logic and ensures payload shape.

2. Enforce Invariants

   • Money: Must be >= 0.
   • Harmony: Must be > 0 (or triggers Game Over).
   • Inventory: Items must be unique IDs.
