// The visible list is derived during render from the query. Nothing copies the
// result into state, so there is no second source of truth to fall out of step.
//
// The refresh is an event handler, not an effect, so the panel boots LOADED and
// the skeletons are something the reader triggers. That also keeps
// SidebarMenuSkeleton out of the first paint, which matters because it picks a
// random width in a useState initializer and would otherwise differ between the
// server and the client render. The only effect in the file clears the pending
// timer, so a refresh can never land on an unmounted panel.
//
// `collapsible="none"` is the one Sidebar branch with no media query in it, so
// the panel is identical at every frame width. It ignores the open state too,
// which is why no SidebarTrigger appears here.
//
// `min-h-0` beside the height is load-bearing. SidebarProvider ships
// `min-h-svh`, and tailwind-merge only drops it when another `min-h-*` arrives
// with it, so without the pair the example is viewport tall inside its frame.

`group-data-[side=left]:border-r`, and it is the branch the framed

`mx-0` is a fix, not a preference. SidebarSeparator ships `w-auto`
to undo Separator's `data-horizontal:w-full`, but a variant
selector outranks a plain utility, so the rule stays full width and
the primitive's own `mx-2` then pushes it 8px past the panel's
right edge. In this scrolling content that is 16px of horizontal
scroll on the whole nav; in the footer it is a rule that misses the
left gutter and overhangs the right.
