Backdrop color science — choose intentionally, don't default to white:
• Warm beige/sand → reads as 'premium lifestyle' (skincare, home goods, food). Complements warm-toned products.
• Cool light grey → reads as 'tech/precision' (electronics, tools, SaaS). Complements cool-toned products.
• Deep charcoal/black → reads as 'luxury/dramatic' (watches, spirits, jewelry). Best with metallic or light-colored products for contrast.
• KEY RULE: backdrop should COMPLEMENT, not match. A brown product on beige disappears. A silver product on grey dies. Create tonal contrast.

Shadow type guide — each tells a different story:
• `contact shadow` = product feels grounded, real, sitting on a surface. Best for everyday/accessible products.
• `soft drop shadow` = product feels slightly elevated, polished. Best for premium positioning.
• `hard directional shadow` = dramatic, editorial. Best for fashion/luxury.
• `no shadow, floating on solid color` = clinical packshot, pure product focus. Best for catalog/comparison pages.

Lighting ratio: the prompt uses a 4:2:1 key-fill-rim ratio, which is the commercial photography standard. For flatter/softer looks (beauty, food), try 2:1:0.5. For dramatic/moody (spirits, tech), try 8:1:2.

Tips: name ONE surface + ONE backdrop color for consistency across a catalog. Add `reflective surface` for a glossy tabletop look. Keep `--stylize` at 100–200 so the product stays accurate — higher values add artistic interpretation that distorts product truth. Generate 4 variations, upscale the one with the cleanest shadow and truest color. For hero images, try `--ar 16:9`; for product cards, `--ar 1:1`.
