Earthdata Proxy URL Resolver (plugins/earthdata-relay.ts)

Identifies NASA Earthdata URLs and routes them through a CORS-enabled proxy endpoint, enabling token-authenticated access to protected geospatial datasets.

// load it at boot (earthdata-fetch-auth.ts) without pulling in the plugin.

/**
 * GeoLibre's tiles Worker route that streams a protected Earthdata file with
 * CORS (`workers/tiles/src/earthdata.ts`). The DAACs send no CORS headers, so
 * the browser build downloads through it, and COG map layers on every build
 * read through it: the layer keeps this token-free URL, and the host adds the
 * Earthdata Login token to requests under it (`earthdata-fetch-auth.ts`).
