// In the activity rows the timestamp is the last span, and the menu button
// applies `truncate` to whichever span comes last. Giving the timestamp
// `shrink-0` and the label `min-w-0 flex-1` puts the ellipsis back on the text
// that actually needs one.
//
// `absolute h-full` is what keeps the panel inside the example. This is the
// desktop branch, whose container ships `fixed inset-y-0 h-svh`, and a fixed
// box neither reads the provider's height nor is clipped by its
// overflow-hidden, so it would be window tall against the right edge of the
// page. The className lands on that container and tailwind-merge swaps both
// groups; the provider's `relative` is what it then measures against, and its
// overflow-hidden is what finally clips the off-canvas slide to the example.

// The same parts doing a second job: a right-hand inspector beside the record
// it describes, rather than a navigation panel.
//
// The children are in INSET-FIRST order, and that is what puts the panel on
// the right. `side="right"` only decides which edge the fixed container pins
// to; the space it occupies comes from a spacer rendered in flex order, so a
// Sidebar written before the inset would reserve its column on the left.
//
// `variant="floating"` draws its own chrome, a padded container with a ring
// and a radius that every style resolves for itself, so there is nothing here
// to hand-roll a border or a corner for.
//
// `collapsible="offcanvas"` means the panel can be entirely gone, so
// SidebarTrigger in the inset header is what brings it back. SidebarRail is
// left out rather than unavailable: it ships `tabIndex={-1}` and `sm:flex`, so
// it would add a second control for the one toggle that only a mouse on a wide
// frame can reach. Under 768px shadcn's Sidebar swaps to a Sheet and that same
// trigger opens it.
//
// `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.
