"""
Platform model representing a business offering/product line.

Platforms are independent business products (e.g., OMS, Loyalty Program, Site Builder)
that can have their own:
- Marketing pages (homepage, pricing, about)
- Store default pages (fallback storefront pages)
- Subscription tiers with platform-specific features
- Branding and configuration

Each store can belong to multiple platforms via the StorePlatform junction table.
