 * File contents must be exactly `<token>\n` — no CRLF, no extra whitespace, and
 * the token body must match `[A-Za-z0-9_\-+=/.]+`. Strict validation up front
 * prevents hard-to-diagnose bearer-token mismatches later.
 *
 * A leading `~/` in `tokenFile` is expanded to `os.homedir()` so configs using
 * the common `~/.mma/auth-token` pattern work without the caller
 * having to resolve it first.
