 ## 3) Scope & principles
 - **Website ↔ Panel on the same host.** Website uses the **panel DB for authentication** and the **panel’s internal APIs** for provisioning. **Sessions remain separate** (website session ≠ panel session).
-- **Billing module flexibility.** The `modules/billing/` frontend can run on the **same machine as the panel** or on an **external web host**, interfacing primarily via MySQL table edits. All interaction with panel DB happens through direct MySQL queries using credentials in `modules/billing/includes/config.inc.php`.

All interaction with panel DB happens through direct MySQL queries using credentials in `modules/billing/includes/config.inc.php`.
+- **Billing module is STANDALONE.** The `modules/billing/` frontend is a **standalone product** that can run on the **same machine as the panel** or on an **external web host**. It must **NEVER** use `require_once` to include panel files like `includes/database_mysqli.php` or any panel helper functions. Instead, it connects directly to the MySQL database using standard `mysqli_connect()` with credentials from `modules/billing/includes/config.inc.php`. All database operations must use native mysqli functions (mysqli_query, mysqli_real_escape_string, etc.), NOT panel-specific helper functions like `$db->query()` or `createDatabaseConnection()`.
 - **Catalog = XML.** Enable **every game** present under `modules/config_games/server_configs/`. The website reads those XMLs for ports, params, install/update metadata. New XMLs should become available without code changes.
 - **Regions/Nodes = panel DB.** Regions and nodes are configured in the panel and must be **queried live** from the panel DB. Never hardcode or mirror region lists on the website.
 - **Slotless model.** Pricing/UX must not enforce slot caps. If an engine requires a player count parameter, set a safe high default and surface engine limits transparently if they exist.
