keep the gateway thin.

الموضوعات المخطط لها

• No business rules (pricing, discounts, order validation); they belong in services.
• No data aggregation that grows into a service of its own (see BFF).
• No shared database access, and no per-service special cases that need constant redeploys.
• Keep it stateless and fast; every request pays its cost.
• A gateway that every team must change for each feature becomes a new monolith and a bottleneck.
