Reviewed both pages at desktop and phone widths. Desktop was fine; on
phones three things were wrong. The top bar wrapped into four rows
because the font-comparison pill and full-size links all stayed; on
screens under 640px the pill is hidden and links and buttons tighten.
The dashboard menu rendered as five full-width blocks because the
wide-screen width:100% rule outranked the phone override; it is now a
row of pills, the wallet block collapses to one line (short address,
live balance, refresh), and the sub-tabs scroll sideways instead of
wrapping. The long address had also been pushing the whole page wider
than the viewport, fixed with minmax(0,1fr) on the grid column.
The market showed an empty filter bar and a one-line status when there
were no listings; it now shows a proper empty state with the two things
a visitor can do (sell from the dashboard, register a new name) and
hides the filters until there is something to filter. Buy buttons go
full width on phones.
