// QuotaProvider is the seam a managed deployment uses to enforce plan
// limits, exactly like AuthProvider is the seam for identity. The
// open-source server ships only UnlimitedQuota; billing and plan logic live
// outside this repo. Hooks fire on every write path (browser uploads, the
// device sync store proxy) and on seat growth, keyed by org id.

	// CheckSeat runs before an invite adds a member; members is the current
	// count. A non-nil error rejects the join.

	// RecordUsage runs after a write succeeds, for accounting.
