saod-ux/e-view ? reverse-engineered prompt

Build me a multi tenant e commerce app for abaya designers and merchants in Kuwait.

I want a polished storefront for each merchant on their own subdomain or custom domain, plus a shared dashboard where they can manage products, orders, customers, shipping, coupons, and team access. It should also include a tailor portal for production work, where a merchant can invite a tailor to view and manage assigned orders.

Use the current E view brand style for any UI, landing page, and copy, and check the brand files before designing anything. Make the app feel production ready, with Supabase auth, secure tenant isolation, payments for MyFatoorah and Tap, abandoned cart emails, order expiry cleanup, and error monitoring. Keep it ready for Vercel deployment and use the existing app structure if possible.

If you need anything unclear, look up the current docs online and then wire it up cleanly.
