 `SidebarRootComponentProps` composes the layout owner share, the global `useSessions` and `useWorkspaces` hooks, the declared `sidebar.workspaces` and `sidebar.settings` child slots, and injected `startSession` plus sidebar-toggle callbacks. There is no plugin store.

+During a live collapse, the shell holds the expanded content at its current width while it fades out for 150ms. The four upper controls—the shell toggle and New Session plus add and search rendered through `sidebar.workspaces`—then share one 150ms fade and 49px leftward translation into the 56px rail, ending with the layout's 300ms column slide; every 36px control box follows the same path to the rail's 10px left inset. The bottom-pinned `sidebar.settings` control shares the fade timing but has no horizontal translation. A page that starts collapsed renders the rail statically, and reduced-motion mode disables both transitions.

 Scrollbars in the column are a pointer affordance: the shell rebinds ui-theme's [scrollbar indirection](../ui-theme/README.md) to `transparent` whenever the pointer is outside it, and keeps the thumb drawn for 2s after the pointer leaves, so a list nobody is pointing at carries no bar. The reservation that keeps rows from moving belongs to the scrolling region ([ui-workspace](../ui-workspace/README.md)), so revealing a thumb never reflows.

 The foot is the `sidebar.settings` seat: the sidebar renders only the bottom-pinned layout slot and shares its column state (`wide`); ui-settings registers the trigger row and settings panel there.
