* =============================================================================

* Replace YOUR_LIMITED-ACCESS_API_KEY with your actual 16-character API key from:
* https://www.torn.com/preferences.php#tab=api
*
* Required Access Level: Limited Access
*
* =============================================================================
* 📋 CATEGORY MULTIPLIERS - EDIT THESE TO ADJUST YOUR PRICING STRATEGY
* =============================================================================
*
* These multipliers are applied to the market price for each category.
* Values below 1.0 will price below market (more competitive).
* Adjust based on your desired profit margins and market competitiveness.
