+### 2026-06-03 — frontend@HEAD — Mini App in-shell shopping cart (v2.8.59) — buyer-parity phase 1
+
+**Why:** Goal: full buyer-role parity in the Mini App (then other roles). Phase 1 = cart.
+New `useTelegramCart` hook shares the web checkout's localStorage key
+(`app-request-template-checkout`) so the Mini App cart IS the web cart; new `TelegramCartView`
+(qty stepper, remove, total, checkout → web); add/remove-to-cart buttons in the in-shell seller
+shop; cart badge + overlay in the shell.
+**Buyer-parity roadmap (remaining):** offers view/accept on requests → delivery confirmation →
+payments list → points/referral → addresses CRUD → TON Connect payments (Telegram Wallet is
+TON-only, no EVM; backend already has tonProofService).
+**Verification:** tsc + eslint clean. Admin verifies: فروشگاه → افزودن به سبد → سبد → ادامه و
+پرداخت → web checkout shows the same items.
