In-Memory Session Store

// ignore_for_file: file_names, avoid_print

// ============================================================================
// 35 — IN-MEMORY SESSION (NO FILE LEFT BEHIND)
// ============================================================================
//
// MemorySessionStore never touches disk — the auth key lives only for the
// life of the process. You'll have to log in from scratch (phone/code/2FA,
// see 01_login.dart) every single run, but nothing persists afterwards.
// Good for CI, one-off scripts, or anywhere you don't want a session file
// with real account access sitting around afterwards.
//
// HOW TO RUN:
//   dart run example/35_memory_session_store.dart
//   (it'll ask for a login code every time — that's expected)
// ============================================================================
