11   * (cold getClaudeAIOAuthTokens memoize → sync `security` spawn, ~60ms/call,
12   * ~180ms total in profile v5 when token refresh cleared the cache mid-session).
13   * GB is a cheap cached-map lookup and stays outside the memo so a mid-session
14   * kill-switch flip still takes effect on the next render.
15   *
16   * authVersion bumps on /login only. Background token refresh leaves it alone
17   * (user is still authed), so the auth memo stays correct without re-eval.
