Marigold Book on Yellow Field

[Format] Landscape 16:9 gig cover, one-product hero render on a flat colour field. Clean 3D studio realism, soft directional light, gentle drop shadow. No watermark, no personal names. [Layout] A single saturated marigold-yellow field fills the entire frame. One matte black hardcover book is the only object, floating near the centre-left and tilted roughly twenty degrees counter-clockwise so its spine runs up the left edge, the front cover facing the viewer and the page block just visible along the bottom lip. A soft grey shadow pools beneath the book's lower-right corner and anchors it to the plane. No border, no other element; the vast empty yellow above and to the right of the book is deliberate negative space. The cover face itself divides into three bands — a two-line white title block at the top, a large flat yellow glyph filling the middle, and a small white web-address line at the bottom right. [Subject] None — object only. The book sits raised off the ground plane by its shadow, giving a mild sense of levitation. [Headline] Top-left of the cover, a two-word title stacked on two lines: the first word in heavy white sans caps, the second directly below in a thin light white sans at the same size, flush left. Across the lower half a huge flat yellow mark — an angular bracket-like monogram built from thick vertical and horizontal bars with rounded corners — bleeds to both side edges. Bottom right, a tiny white lowercase web address; the spine carries a small vertical white wordmark. [Badges] None. [Mood] A single vivid marigold-yellow field against matte black; graphic, confident, poster-simple. At thumbnail scale the yellow frame holding one tilted black book still reads instantly at forty pixels.
