//
// Single source of truth for the active tenant root in Firestore + Storage.
//
// Library Loot is multi-tenant: every Firestore doc lives under the active
// tenant's top-level collection. Code anywhere in the app that needs a
// Firestore reference must go through THIS module — never hardcode a tenant
// ID. When the app eventually resolves the tenant from hostname / claims /
// route, only this file changes.
//
// Storage paths follow the same convention: every object lives under a path
// that begins with the tenant ID.
