black-and-white manga horror panel, narrow apartment corridor with repeating doors, single ceiling light flickering, deep shadows pooling at the corners, a thin draft visualized by subtly bending hanging tags and hair strands, a tenant holding a key close to the lock with tense fingers, micro-expression: widened eyes, tight mouth, sweat bead, meticulous ink lines, heavy blacks with controlled negative space, fine crosshatching on walls and floor tiles, claustrophobic perspective with strong vanishing point, quiet dread, realistic anatomy, high texture detail, printed manga grain, no explicit violence, suspenseful stillness
