 ### Brand and New Session
 
-The expanded brand row renders `sidebar.brand.mark` and `sidebar.brand.name` as independent single slots; the collapsed rail renders the same mark slot. On Web and Windows desktop, clicking the expanded brand starts a new session; hovering or focusing it shows no tooltip. Without occupants, the shell uses the fish mark and a localized local-build label. A complete build stacks a code badge below the label as `version[-commit][-dirty]`, using `DSH_CLIENT_VERSION`, the optional 7-character `DSH_CLIENT_COMMIT_HASH`, and `DSH_CLIENT_GIT_DIRTY=true`; missing version metadata omits the badge. New Session targets the explicit Workspace used by a scoped action, otherwise the current Session's Workspace, otherwise the most recently active Workspace; when none exists it clears into the blank New Session page. The expanded New Session button displays the effective binding as trailing grey text on hover or keyboard focus. While the shortcut is visible, the centered icon and label fade before it when space is narrow; CSS reserves the shortcut’s width without measuring the button. Icon-only controls retain tooltips with platform-formatted keycaps, including the resident macOS header control when the sidebar is hidden. All controls expose `aria-keyshortcuts`.
