Design a responsive web app for "CheckPrice SL", a price-checking and product comparison tool for Sierra Leonean markets. Users should be able to view and compare real-time prices of common products (like rice, oil, sugar, etc.) from different sellers across various marketplaces.

The app should have the following key pages:

1. Homepage:

   • Hero section with a short tagline: “Don’t Guess the Price. Check It.”
   • Call to action: “Search Prices” and “Contribute a Price”
   • Simple search bar for product name and market location.
   • Trending products or most searched items.

2. Search Results Page:

   • A list of matching products with:
     • Product name
     • Market name
     • Seller name (optional)
     • Price (in Leones)
     • Last updated time
   • Sort by: Price (Low to High), Most Recent
   • Filter by market or product category

3. Add Price Page:

   • Form for users to submit:
     • Product name (dropdown or text)
     • Price
     • Market location
     • Optional: Seller/shop name
     • Date of price

4. Product Details Page:

   • Summary of prices for a specific item
   • Price history chart
   • Contributor info (if verified)
   • Button to “Update Price”

5. Admin/Moderator Dashboard (basic layout only):

   • Approve/reject price submissions
   • View flagged entries
   • Manage users or verified sellers

Design style:

• Use a clean, modern design with Tailwind CSS
• Prioritize mobile-first layout
• Use icons for category filtering (food, electronics, household, etc.)
• Include light and dark mode toggle

Tech stack planned: V0 for UI, TypeScript/React, Supabase or Firebase for backend later.
