## Overview

EnvyEnv is a small location-based helper module for fetching weather and terrain data. The documented user workflow is to provide a geographic location and obtain those results through the package entry point. Weather includes climate classification, and the repository includes a Köppen-Geiger raster. The weather implementation and entry point were not sampled, so their internal dispatch and raster usage remain unverified; those links are shown as dashed rather than asserted.

Main entry points: [`src/index.ts`](https://github.com/platformer444/envyenv/blob/main/src/index.ts) (Package entry), [`src/weather.ts`](https://github.com/platformer444/envyenv/blob/main/src/weather.ts) (Weather retrieval), [`src/terrain.ts`](https://github.com/platformer444/envyenv/blob/main/src/terrain.ts) (Terrain retrieval), [`data/Koppen-Geiger.tif`](https://github.com/platformer444/envyenv/blob/main/data/Koppen-Geiger.tif) (Climate raster)
