Strong rule: style --- Studio Ghibli aesthetic, detailed hand-drawn textures, warm cinematic lighting, cozy mountain observatory interior, snowy apocalyptic exterior, 4K ---. Absolute profound black void screen, immersive infinite darkness evoking cosmic abyss or final peaceful nothingness post-story. Full-frame uniform blackout with ultra-subtle textured depth from imperceptible digital noise mimicking distant star dust or fading ember glow. No defined camera angle, pure enveloping immersion. Lighting completely absent, total shadow. Contemplative mood of audience exhale and deep introspection, ultimate serene closure atmosphere. Monochromatic deepest obsidian black palette with faint gradient abyssal layers, minimalist cinematic elegance.
