Dev mode (DEV_DEFAULT = true for now, backtick toggles it at runtime) unlocks Explore mode, stratum browsing and the inspector panel. Without it the map screen always opens in Walk mode and Tab and i are inert. The minimap now lives in the lower part of the inspector panel; the player's own map will be a different thing later.
