- Move controls (band selector, grid toggle, nav links) to a docked right sidebar on desktop, keep floating overlay on mobile - Point detail panel floats over the map bottom-left instead of inside the narrow sidebar - Add collapse/expand toggle for the sidebar - Add auth links (login/logout/settings) to sidebar - Wrap public live routes in live_session with UserAuth on_mount - Use daisyUI menu lists for sidebar navigation
