        "en": "Ultra-photoreal beauty campaign contact sheet on a pure white seamless background. A 3x3 grid collage of nine panels featuring ONE model with hair worn down: voluminous, glossy, long dark waves with soft movement and lift at the roots. The model has a lean, fit, runway-like physique and an attractive high-fashion look. Skin is luminous with realistic texture and refined editorial retouch (no plastic smoothing). Makeup: defined brows, clean eyeliner, soft bronzy blush, and bold red lipstick.\n\nProduct must stay consistent: a sleek chrome lip product tube and doe-foot applicator with the brand name '{argument name="brand name" default="BAGEL"}' printed clearly on the tube in a bold modern sans-serif. The tube shape, cap, chrome finish, and label placement remain consistent across all panels. The word '{argument name="brand name" default="BAGEL"}' is readable, spelled correctly, centered, and aligned on the tube in every panel where the product is visible. No other text or brands anywhere.\n\nPanel variety (9 frames):\n1) Model holds the chrome tube horizontally over the eyes like a visor; lips puckered.\n2) Close-up applying the red lipstick with the doe-foot applicator; tube visible with '{argument name="brand name" default="BAGEL"}'.\n3) Model laughing wide-mouth; tube held near face.\n4) Beauty angle portrait holding tube near chin; confident gaze.\n5) Extreme close-up smile with teeth; tube held lightly between teeth; '{argument name="brand name" default="BAGEL"}' readable.\n6) Wink + playful tongue-out; holding applicator and tube; '{argument name="brand name" default="BAGEL"}' readable.\n7) Applying lipstick again with elegant hand pose; manicure clean nude/white.\n8) Kissy face wink; cheek highlight strong and glossy.\n9) Tight crop smile; crisp lip texture and clean edges.\n\nLighting: high-end beauty studio lighting, bright and even, soft specular highlights on chrome packaging, realistic shadows, face and product both tack sharp. Composition: clean margins, consistent spacing between panels, magazine-quality production. No watermark, no extra logos."
