- Space switcher: clamp menu left to prevent right-edge overflow,
add max-width: calc(100vw - 8px), scrollable tabs with smaller
padding on mobile
- Auth/edit modals: add max-height: 90dvh + overflow-y: auto so
virtual keyboard doesn't push modal off-screen, reduce padding
on small screens
- Identity dropdown: raise z-index from 100 to 10002 so it renders
above the app-switcher sidebar (10001)
- Device nudge toast: constrain max-width to viewport width
- App switcher: add translucent backdrop overlay on mobile (<640px)
with tap-to-dismiss
- Add :active pseudo-class alongside :hover on interactive elements
for touch tap feedback
