Create a square 1:1 luxury beauty product advertisement for a debranded amber perfume bottle. Show one classic rectangular glass bottle as the hero object, placed upright slightly right of center on a polished black marble surface with fine white veining and a clean mirror reflection below. Use a faceted transparent stopper, thick clear glass walls, and a warm amber liquid that appears luminous from within. Cover the bottle lightly with realistic condensation droplets for texture. Build a dark studio background with soft atmospheric smoke curling on both sides, leaving the center clean for product focus. Light the scene with a strong warm key light from the upper left, a subtle rim light along the bottle edges, and a soft golden bloom in the far background; keep contrast high, shadows deep, and glass highlights crisp. Color palette: black, amber gold, warm bronze, and soft ivory highlights. Typography layout: place the headline "Signature Scent" in a clean premium sans-serif at the upper center or upper left; keep the bottle label generic with minimal non-branded placeholder text only, no logos, no known brand wording, no creator marks, no prices, no badges. Preserve a commercially usable visual hierarchy: headline first, bottle second, atmosphere third. Product photography finish must be photorealistic, sharply focused on the bottle, with shallow depth of field in the background, realistic reflections, premium material rendering, and advertising-grade retouching. Negative constraints: do not include any real brand names, monograms, watermark-like corner marks, celebrity associations, social handles, pricing, exaggerated claims, or copied label text; do not reproduce the original reference exactly; do not add extra objects unless they are subtle atmospheric accents.
