Safely load environment variables in Node.js with fallback support.

function getEnv(keys, fallback = {}) {
    const result = {};

    for (const key of keys) {
        const value = process.env[key] ?? fallback[key];
        if (value === undefined) {
            throw new Error(`[simple-env-reader] Missing environment variable: ${key}`);
        }
        result[key] = value;
    }

    return result;
}

module.exports = { getEnv };
