 ## 0.1.N MVP UI And UX

- [ ] Add main menu placeholder.
+- [x] Add main menu placeholder. Added native `UAgrarianMvpFrontendWidget` with a scalable painted main menu panel and local player-controller spawning so the MVP frontend has an owned placeholder instead of relying on template UI.
 - [ ] After splash/startup screens, land on an MVP character selection landing page.
 - [ ] Let players choose a realistic young adult male or female character with average proportions for the MVP.
 - [ ] Add join server screen.
