Edge cases + gotchas

• No split records are created for orders at the moment; Payment Splits pages are empty.
• Direct to Vendor doesn't change checkout — customers still pay you.
• No gateway splitting — Razorpay Route, PayU split settlements and similar aren't used.
• Two commission sources — splits would use the seller's profile commission rate; the Commissions module uses Commission Rules.
• Single-seller stores don't need this module.
