Book cover illustration, vertical 2:3, cinematic oil painting. An adult Slavic woman in her early forties, tired intelligent face, three-quarter view, standing at a dark kitchen window at night. Simple clothes, dark hair, no armor, not a girl, not a warrior. One hand on the glass. Outside the window: not a city street — a black ocean under an eternal night. Sky is bruised deep purple, heavy, no sun, no moon, no stars. In the far distance a single lighthouse beam, warm amber, cutting through fog — the only light that should not exist here. Inside: ordinary kitchen, faint warm lamp. Contrast: mundane interior vs impossible myth outside. Mood: intimate, melancholic, a moment of recognition. Palette: blacks, deep purple, one amber accent. Leave the upper third dark and empty for a title overlay later. Style: painterly, detailed, slightly grainy, literary fantasy book cover, not anime, not photoreal celebrity, not horror. No text, no letters, no watermark, no logo.
