Every quote waited for an operator before it could be paid, so an order placed at night waited for the morning. A cart the Site priced is now approved when the quote is created, through the same server pricing the operator's approval uses (app/quote_review.py). Orders above QUOTE_AUTO_MAX_METRES (50 m) and items claiming a discount on art the Site could not analyse still wait for review; the Kanban shows which quotes were approved automatically and why the others wait. The grade is still computed in the browser (roadmap 3.2, 3.9), so the discount remains a customer-supplied value until the server computes it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
