 - [x] Add interaction prompts. Promoted the existing centered interactable prompt renderer into the 0.1.N UI pass with `AgrarianToggleInteractionPrompts`, keeping prompt text driven by focused interactables.
 - [x] Add death/respawn UI. Added a dedicated dead-state MVP panel with last death reason, Ground Zero respawn context, and `AgrarianToggleDeathRespawnUI` while preserving the existing server-authoritative respawn command.
 - [x] Add debug/dev menu. Added a toggleable `bShowDebugDevMenu` HUD panel plus `AgrarianToggleDebugDevMenu`, listing the core MVP frontend, UI, persistence, and recovery commands for tester/admin use.
-- [ ] Add accessibility basics.
+- [x] Add accessibility basics. Added runtime MVP UI scaling with `AgrarianSetUiScale 0.75-1.5` and a frontend high-contrast mode with `AgrarianToggleHighContrastUI`, applying scale to the native frontend and HUD text surfaces.
 - [ ] Ensure UI scales on common resolutions.
