Bring the seller page mobile header in line with the design / desktop:
replace the plain top bar + centered logo with a cover banner, a floating
circular back button (safe-area aware), an overlapping rounded logo, the
store name + verified badge + @handle, a clean borderless stats row
(محصول / دنبالکننده / امتیاز), the description, and follow + message-icon
actions. Search bar and product masonry unchanged. Desktop untouched.
