operational guidance (Iris Plaza official notice, Nov 5)

### Tip: if you used Iris Plaza, rotate any reused password and ignore lookalike emails, SMS or sites asking for passwords or cards

- Change the Iris Plaza password anywhere else you reused it; some stored passwords were encrypted, but reuse is still the risk.
- Do not open attachments or links in unexpected mail or SMS, and do not give personal details, IDs, passwords or card numbers to lookalike sites or social accounts.
- Official contact listed in the notice: Iris Plaza contact center 0120-108-824 (weekdays and Saturdays 9:30 a.m.–5:00 p.m. Japan time) or `plaza_info@irisplaza.co.jp`.
