Book cover, dark and atmospheric. Interior of an old Soviet apartment, dim and claustrophobic. An empty wooden chair sits alone in the corner, emitting a faint warm amber glow around it — as if someone invisible is sitting there. Old yellowed wallpaper with faded diamond patterns, lighter handprint-shaped spots on the walls. A single ceramic mug on a bare kitchen table, warm to the touch. In the far corner, barely visible — a small hunched silhouette, dark, featureless, patient. A murky window with cold grey-blue light. Worn dark parquet floor. Muted desaturated palette, sepia and charcoal tones, heavy vignette, subtle film grain. Title text "ТИХАЯ КОМНАТА" at the top in aged serif font, faded warm grey. Mood: existential dread, quiet horror, slow decay, warmth that suffocates. No blood, no gore, pure atmosphere. Russian provincial ghost story aesthetic. No text.
