Sidebar
The app shell's primary nav: 240px (--sidebar-w) collapsing to a 56px icon rail, sidebar fill (a surface-2 alias) on a hairline, no shadow. The current section is primary text plus a 2px primary edge, never a filled pill, and carries aria-current="page". On touch devices (phones and tablets, any orientation) and below 768px it becomes a Sheet overlay; fine-pointer devices from 768px get the push panel.

Press ⌘B or the trigger to collapse to the 56px rail.
Floating
The floating variant detaches from the edge: rounded corners, a border, a soft shadow.
Inset
The inset variant keeps its own panel flat; the rounded border lives on the inset content instead.
Anatomy
Rail, loading skeleton, a group action and a row action, a separator, and the right-side offcanvas variant.
