Coloured with scandinavia-01 · SNÖ — first snowfall, frozen lake; the coolest white in the library. Reads as a Nordic naval chart: frosty body, deep-teal command rules, brick-red mine alerts.

Palette pulled from Rangrez, the global colour-palette library that backs all NakliTechie projects.

Want to remix this game with new chokepoint maps? Here's how:

Open auto-sampler.html in your browser. This tool:

1. Loads the map at a specific lat/lng and zoom level using Leaflet + CartoDB tiles
2. Locks the view to prevent scrolling/zooming
3. Samples tile colors to detect water vs land:
   • Water = blue-dominant pixels (B > R + 15)
   • Land = cream/white pixels (high RGB, R ≥ B)
4. Generates a 35×19 mask array where 0 = water, 1 = land
5. Outputs the mask ready to paste into index.html

1. Pick a location (e.g., Suez Canal, Panama Canal, Malacca Strait)
2. Find coordinates that show the chokepoint clearly at zoom 8-9
3. Edit auto-sampler.html:
   • Change center: [lat, lng] to your coordinates
   • Adjust zoom level (8-10 works best)
4. Run the sampler:
   • Wait for tiles to load
   • Click "🔒 LOCK MAP"
   • Click "🤖 AUTO-DETECT WATER"
   • Adjust threshold if needed
   • Manually fix any errors by clicking cells
5. Add to index.html:
   • Copy the generated mask
   • Add a new entry to the MAPS object with:
     • name: Display name
     • subtitle: Tagline for the map
     • center: [lat, lng] for the map view
     • zoom: Zoom level (8-10)
     • mask: Your sampled mask array
     • ticker: Region-specific news messages (8-12 items)
   • Add map-specific win/lose messages
6. Add map selector option in the HTML dropdown

• Zoom level matters: Higher zoom = more detail, smaller coverage
• Threshold adjustment: If auto-detect misses water, increase threshold; if it detects too much, decrease
• Manual cleanup: Always review and click to fix stray cells
• Test alignment: The grey overlay should match visible coastline

Chokepoint — same maps, different genre. A tower defense game where you build coastal batteries and hold the strait against waves of enemy ships.
