Strong rule: style --- Studio Ghibli aesthetic, detailed hand-drawn textures, warm cinematic lighting, cozy mountain observatory interior, snowy apocalyptic exterior, 4K ---. Vast bruised twilight sky over forested mountain valley, heavy clouds rolling low pregnant with snow, distant ridges fading to silhouettes. Epic wide high-angle vista dominating frame. Dimming purple-blue twilight fades warmth to chill, ominous deepening shadows. Rising urgency as day wanes perilously. No characters foreground, pure environmental menace building. Stormy indigos, fading oranges on horizon, stark white peaks.
