- Stack the extensions page header vertically on small screens, let the
filter Tabs scroll horizontally if they overflow, hide the debug
button label below sm and let the install/debug controls wrap.
- Constrain the debug popover and its inputs to the viewport width so
they no longer overflow on phone-sized screens.
- Drop the card grid from a fixed 30rem column to a min(100%, 22rem)
column at base / 28rem at sm, and reduce the gap, so cards render
cleanly at 360px+ widths in both flat and grouped views.
- Make the add-extension header actions wrap on lg- viewports and the
install dialog responsive instead of a hard 500px box.
