Title: Nacre — The Shape of a Memory Exact creative prompt: Create a fictional luxury fragrance art direction called Nacre. Use a pearl and dusty lilac palette, enormous translucent serif backdrop wordmark, and a dimensional glass perfume bottle drawn only with CSS gradients, inset shadows, a metallic cap and a cream label. Surround it with sparse editorial copy and a flattened luminous halo. Three scent-note buttons should change the poetic description and atmosphere. Responsive mobile composition, no external resources, inline CSS and JavaScript, reduced-motion consideration. Description: A softly luminous fragrance campaign with a central sculptural bottle, suggesting pearlescent glass and an intimate remembered atmosphere. Major visual techniques: Layered translucent gradients; simulated glass refraction; metallic cap; giant low-contrast type; elliptical halo; atmospheric radial backgrounds. Intended interaction model: Explore the top, heart and base fragrance notes and hover the bottle for a gentle lift.
