// Runtime env values that must reach the client bundle. Rspack resolves
// `process.env` at BUILD time to an empty-ish polyfill in the browser, so
// any value we want per-deployment (e.g. MAP_TILE_URL pointing at a tile
// service that the local ingress doesn't proxy) has to be injected into
// the HTML as a window global. getEnv() picks up window.__ENV__ on the
// client. Evaluated once at Modern.js build time → pod env → HTML.
//
// IMPORTANT: Rspack's HTML plugin preprocesses <script> children through
// a template engine that eats '{token}' pairs AND decodes \u007B / \u007D
// Unicode escapes before running the engine, so neither raw braces nor
// escaped braces survive. The Leaflet tile template literally contains
// '{z}/{x}/{y}', so we serialize the whole payload to base64 and decode
// it in the browser at runtime. Base64 output is A-Z/a-z/0-9/+/=/ — no
// braces for the template engine to grab.
