/**
 * Desktop env preloader for Next.js.
 *
 * Why: Next.js only auto-loads `.env*` (e.g. `.env`, `.env.local`, `.env.development`),
 * but our desktop build expects `.env.desktop`.
 *
 * This file is intended to be used via Node's `-r` (require) flag so it runs
 * BEFORE Next.js loads its own env config:
 *
 *   node -r ./scripts/registerDesktopEnv.cjs ./node_modules/next/dist/bin/next build
