Context

• This was a standard RSU vesting and tax-withholding event, not an open‑market sale or purchase. Withholding of shares to cover taxes (code F) is common and should be viewed as an administrative action rather than a directional bet by the insider. The filing appears timely (filed within two business days of the April 24 transaction).
