The duplicate-hamburger fix removed our custom off-canvas sidebar on
mobile, deferring to Odoo's own small-screen navigation (.o_menu_toggle
-> .o_app_menu_sidebar, from web.NavBar.AppsMenu.Sidebar). That native
drawer is driven entirely by Odoo's own ui.isSmall JS check, independent
of any breakpoint here, and was never themed, so it fell back to stock
white/purple Odoo styling while the desktop .o_sidebar_custom sidebar is
fully branded. Re-skin .o_app_menu_sidebar (topbar, section list, app
list) with the same teal gradient so mobile and desktop match.
