A travel advisory company is launching a customer-facing product experience for browsing and requesting travel services. You are given mockups for three UI pages:
1. A catalog or search page showing travel products such as trips, destinations, packages, or advisor-curated experiences.
2. A product detail page showing descriptions, itinerary highlights, images, pricing, availability, destination metadata, and related advisors.
3. An inquiry or booking-request page where a traveler submits contact details, preferred dates, party size, budget, and special requirements.
