Hyper-real 3D render: brownie inside a bomb shelter

Ultra-realistic 3D render of a fudgy chocolate brownie on a dented metal tray inside a bomb shelter. Cold concrete walls with chipped paint, dusty shelves, a rusty generator, and a bunk bed in the background. Fluorescent emergency lights cast a harsh greenish-yellow glow, with drifting dust motes and a subtle hazy atmosphere. The brownie has a glossy top, deep chocolate color, and visible moist crumb at the edge; a thin glaze catches the light. The tray and surroundings show scratches, rust, and wear. Shot from a low angle with a 50mm lens, shallow depth of field so the brownie is in sharp focus while the back room blurs softly. Rendered with physically based rendering (PBR) at high resolution, showcasing realistic textures, subtle rim lighting, and soft shadows. Mood: quiet, tense, yet comforting as a small treat in an austere shelter.
