Create a photographic teaching illustration, portrait 4:5 composition, 1280 by 1600 pixels. A quiet independent bookshop reading desk at night. Exactly one open book in the lower-middle right, fully inside frame, cream blank-looking pages with subtle paper and binding details but no readable writing. One small warm desk lamp on the left of the book, its shade and stem confined to the lower half, stem clearly separate from the book spine; the warm illumination falls on the book pages, shade material visible and not a blown-out white patch. A small window in the upper right contains only a few dim cool distant lights, no neon signage, its frame separate from the book outline. Reserve the upper-left area as a continuous dark charcoal warm wall with even low detail and no objects, hard shadows, bright spots, or window frame, enough room to typeset a short event heading later. Calm natural indoor photographic texture; soft warm paper against restrained cool night tones. No people, no additional books, no cup, no pen, no letters, logos or watermarks. This is an illustrative image for an educational article, not a result attributed to LocalBanana or a controlled model comparison. No embedded captions or annotations.
