- Banner editor in store edit: color swatches + custom color picker, or
image/GIF upload with a 1600x500 dimension hint. Renders the chosen banner
(image cover / solid color) on the public seller page, falling back to the
default gradient.
- Sellers list: drop the desktop name overlay (match mobile, image-only tiles).
- Seller page mobile header: chat moved top-left under the banner, search+filter
beside the follow button, followers/product counts removed (rating kept),
compacted so products fill more of the screen, circular logo, thinner action row.
