━━━━━━━━━━━━━━━━━━━━━

🚦 1. Intuitive Traffic Light Fuel Price Decision Dashboard

・🔴 Recommended to fill up this week (estimated price increase), 🟢 Recommended to fill up next week (estimated price decrease), 🟡 Fill up as needed on your way.

• Clearly displays the current official prices and estimated new prices for 92 Unleaded, 95 Unleaded, 98 Unleaded, and Super Diesel.

• Visual charts show the amount absorbed by CPC Corporation through its dual mechanisms of "Lowest Price in Neighboring Countries" and "Oil Price Stabilization Mechanism".

• Real-time updates on the international 7D3B average price trend and USD exchange rate fluctuations.

• A countdown timer is released every Sunday at 12:00 PM.

🗺️ 2. Smart Map of 1,989 Gas Stations Across Taiwan

• Complete coverage of all gas stations in 22 counties and cities across Taiwan (CPC, Formosa Plastics, nationwide gas stations, and highway service areas)!

• Automatic location positioning and precise distance calculation using Haversine, supporting real-time sorting from nearest to farthest.

• One-click quick filtering: "Only see directly operated stations", "Automatic car wash 🚿", "Free tire inflation 💨", "Accessible toilets ♿", "Self-service refueling ⚡".

• On-site crowdsourced queue status (smooth, minimal queue, overcrowded) and one-click navigation.

💳 3. Credit Card Fuel Discount Guide
