NavigationFrame is Learn's AppShell without its router and its tabs: a navigation rail from medium windows on with the app's icon on top, leading to the first tab, a bar floating above the foot below, the background of the screen in view around it, and a tick on every choice. TabsStack is Learn's container of the tabs' navigators, every tab kept alive and told whether it shows. Learn's shell is built on both, its tests unchanged; Train's is next. The rail's icon is drawn from 120 px at most in memory, as Learn's was. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Signed-off-by: Tizian 「ティツィアーン」 <raisondetredev@pm.me>
