The Dr Non 3D City Pattern couples two complementary tiers:
Tier 1 Deep Twin (an exact 1:1 block-for-block Minecraft simulation world generated by Arnis from OSM and Overture data) with
Tier 2 Live Web Dashboard (GPU MapLibre native fill-extrusion).

Deterministic Local Linear Projection Formula
ΔX = Math.round((lon - 101.7008) * 111166.5) // Easting in meters
ΔZ = Math.round(-(lat - 3.1413) * 111319.5) // Northing in meters (North = -Z)
Y = Math.round(70 + elevation_or_height) // Altitude above bedrock datum
Command: /tp @p ${ΔX} ${Y} ${ΔZ}
