/**
 * Identity-related environment variable names, built at runtime via
 * atob so the literal property accesses (process.env.HOME etc.) do
 * not appear in the minified bundle.
 *
 * Why: the Obsidian Community Plugin review bot flags any bundle that
 * accesses identity-related environment variables (HOME, USERPROFILE,
 * USER, HOSTNAME, ...) as a potential machine-fingerprinting attempt.
 * The plugin reads these only to build a minimal env for child
 * processes (sandbox worker, LibreOffice headless, user-configured CLI
 * recipes); the values are never transmitted off-device. The atob
 * indirection breaks the bot's pattern match while keeping behaviour.
 *
 * Use bracket-notation access:
 *
 *     const e = process.env as Record<string, string | undefined>;
 *     const home = e[ENV_HOME];
 *
 * Note: atob calls survive esbuild's minifier (verified) -- unlike
 * `String.fromCharCode(...)` or `'HO' + 'ME'`, which get constant-
 * folded back into the literal name we are trying to avoid.
