Create a promotional landing page in a modern, clean, and mobile-friendly design with a “Summer Black Friday” theme. Use a bold and vibrant color palette (e.g., yellow, orange, black) to evoke urgency and summer energy.

At the top, add a full-width banner image of Bali beach at sunset with overlaid text:

• "🔥 Summer Black Friday in Bali 🔥"

• "Limited-Time Hotel Deals – Up to 70% Off"

Below the banner, display a responsive hotel grid (2-3 columns depending on screen size), showing the following information per hotel card:

• Hotel name

• Thumbnail image (placeholder OK)

• Star rating (e.g., ⭐⭐⭐)

• Price per night (KRW), formatted like: "from ₩320,000"

• “Book Now” button (bright, e.g., yellow or red)
