 - [x] Let players choose a realistic young adult male or female character with average proportions for the MVP. Added a selectable MVP character archetype enum, visible selected state, keyboard selection, and `AgrarianSelectCharacter male|female` dev command while keeping both choices on the same MVP survival baseline until real character art arrives.
 - [x] Add join server screen. Added a native `JoinServer` frontend screen showing the selected character and `play.agrariangame.com:7777`, with keyboard flow from character selection and a dev command to display the screen directly.
 - [x] Add loading screen. Added a native `Loading` frontend screen with Ground Zero preparation copy, selected character/server context, a deterministic placeholder progress bar, and join-screen keyboard flow into loading.
-- [~] Add HUD.
+- [x] Add HUD. Completed the MVP HUD pass with a separate `bShowMvpHudFrame` top status frame showing Ground Zero context, alive/dead state, health, food, water, and body temperature, while keeping the deeper developer overlay separately toggleable.
 - [ ] Add inventory UI.
 - [ ] Add crafting UI.
 - [ ] Add interaction prompts.
