Unexpected High-end Product Concepts | Nano Banana Pro

Based on Amir Mušić’s prompt, refactored into a JSON template with two upgrades:

• Reference Image Support
  Locks composition and spatial skeleton; preserves form and redesigns only the “skin” (materials, color, details).
• Brand Style Control
  brand_style toggles brand DNA injection when enabled; defaults to a neutral, premium minimalist aesthetic when disabled.
