Multi-Tenant Architecture
Multi-tenancy is the cornerstone of modern SaaS platforms. Each tenant gets isolated data, custom domains, and independent configurations.

Domain Routing
Incoming requests are routed to the correct tenant based on the request domain, resolved through the domain → site → app → tenant chain.
