 ## 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`.

 - **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.
