#!/usr/bin/env node
// Wrapper that loads `.env` into process.env (without overwriting anything
// already in the environment) and execs the given command. Used by the
// `tauri` npm script so `pnpm tauri build` picks up APPLE_SIGNING_IDENTITY,
// APPLE_ID, APPLE_PASSWORD, APPLE_TEAM_ID etc. without requiring direnv.
//
// Plain shell `source .env` works on macOS/Linux but not Windows; this
// wrapper is platform-agnostic.
