霧の中のファンタジーRPG（Three.js）。一人称・三人称切替と軍隊メニュー

Extend a Three.js fantasy RPG prototype with switchable third-person and first-person cameras. Set the game in a misty, desaturated medieval landscape with a dirt road, rolling hills, reeds, stone buildings and a distant castle fading into fog. In third person, show a hooded warrior with a sword running along the road with a follow camera. In first person, show the hero's arm and blade in view with a small crosshair. Add a key to toggle the camera, smooth movement and a glowing ring marker for points of interest. Include a parchment-styled army screen with a row of creature cards, each opening a detail view with a portrait, stats and a short description, in the spirit of a classic turn-based strategy game combined with an open-world first-person RPG. Use a dark brown and gold UI. Done means the player can roam, switch views and open the army menus without errors.
