+The auth dashboard now includes `Experimental settings` with a manual sync option for `codex-multi-auth`.

+Persist the toggle in `~/.opencode/openai-codex-auth-config.json`:

+When enabled, `Sync now` will auto-discover a `codex-multi-auth` account store from:
+- `CODEX_MULTI_AUTH_DIR`
+- `CODEX_HOME/multi-auth`
+- `~/DevTools/config/codex/multi-auth`
+- `~/.codex/multi-auth`
