AppShellSidebarVariant =
"permanent"|"temporary"
Defined in: components/AppShell/AppShell.tsx:53
How the start sidebar occupies the frame. The axis is the reference
systems' — MUI names exactly this distinction on its Drawer, and Chakra
composes the same two shapes by hand — and it lives on the navigation region
rather than on the shell, because that is the part whose behaviour changes.
permanent— a grid track beside the main region. The desktop shape.temporary— no track: the sidebar lives in aDrawerreached from a trigger in the header row. The shape a viewport too narrow for a track needs, and the answer to a shell that would otherwise overflow.
Choosing between them is the app's call, not the shell's, which is how both references draw the line: the app knows its own breakpoints and whether a pointer is coarse; the shell knows neither.
