Audience: designer + design-AI working on mockups for the Ibiza 100 marketplace surfaces. Goal: lock the common design contract across every marketplace vertical (Villa-Rental, Second-Hand, Wellness, future Yacht-Charter / Boat-Rentals / Beauty & Wellbeing) so a user moves between verticals with zero re-learning while each vertical keeps a distinct identity through photography (NOT chrome color).
This brief compiles what the codebase already enforces today + the open decisions the mockup pass needs to lock.
