TenantFont.tenantId is the organization that owns a custom font, taken from the {tenantId} path segment on the internal fonts endpoints. It scopes every font operation: uploads, listings, and deletes all act within one tenant, and the render engine only resolves a tenant's own fonts when composing its documents. The column is indexed and is the first component of the unique key (tenantId, family, weight), so two tenants can each upload a font named the same family without colliding.
