Aligns with Flutter — there is no bottom nav, drawer, or rail. Every
in-shell screen carries `MainAppBarActions` in its AppBar:
[Home] [Library] [Search] [ ⋮ Playlists / Discover / Settings / Admin ]
The icon for the current screen is suppressed so the action set looks
contextual.
- shared/widgets/MainAppBarActions.kt — NEW. The icon row + kebab.
Takes navController + currentRouteName (FQN) so each screen tells
it which icon to hide. Admin kebab entry gated on `isAdmin` for
later; defaults false.
- shared/widgets/ShellScaffold.kt — NEW. Wraps any in-shell screen
with the MiniPlayer pinned at the bottom (auto-hides on no-track,
matches Flutter `_ShellWithPlayerBar`). Banners slot reserved for
later (VersionTooOld / UpdateBanner).
- nav/Routes.kt — added Discover, Playlists, Requests, Admin,
AdminRequests, AdminQuarantine, AdminUsers, ServerUrl. Grouped
by shell-vs-full-screen comments.
- nav/MinstrelNavGraph.kt — every in-shell route wrapped in
ShellScaffold. NowPlaying becomes a full-screen route with
slideInVertically/slideOutVertically transitions (mirrors
Flutter's CustomTransitionPage modal). Queue / ServerUrl / Login
are also outside the shell.
- MainActivity.kt — drops Scaffold + NavigationBar + the BottomBarTab
list. Just hosts the NavHost now. The MiniPlayer moves into
ShellScaffold per the Flutter pattern.
- library/ui/LibraryScreen.kt — wraps itself in Scaffold + TopAppBar
+ MainAppBarActions (currentRouteName = Library FQN). Accepts
navController; album/artist taps navigate via the controller
instead of via callbacks. Body content still transitional — the
proper 5-tab restructure lands in sub-task 4.
Routes-without-real-screens (Home, Search, Discover, Playlists,
Settings, Admin, Requests, AdminRequests/Quarantine/Users, Queue,
ServerUrl, Login) all render ComingSoon stubs via EmptyState so the
nav graph is fully reachable end-to-end.
