+### 2026-06-04 — frontend v2.8.91 — seller stepper: paid/shop request shows "ship goods"
+
+Buyer stepper confirmed correct (paid shop request → step 4 «انتظار ارسال»).
+Seller side was wrong: a paid shop (template) purchase showed seller step 1
+(«ارسال پیشنهاد») because determineSellerStep gated the step on an
+accepted/hasOffer context the seller view couldn't reliably compute (id seam).
+Since a funded escrow implies an accepted offer for that seller, post-payment
+seller steps are now FIXED/unconditional: pending_payment/payment_pending → 2
+(awaiting payment), payment/processing/paid → 3 (ship goods), delivery → 4,
+delivered/confirming → 5, seller_paid/completed → 6. Removed the unreliable
+`accepted` flag. (Pre-payment states keep the hasOffer 1/2 logic.)
+**Verification:** tsc + eslint clean.
