Context

• This was an RSU vesting and tax‑withholding event — a routine, non‑open market transaction where shares are withheld to cover taxes (a common cashless settlement). It is not a sale signaling immediate cashing out of all vested shares. The filing does not indicate any 10%‑owner transactions or an open‑market sale tied to a trading plan.
