Context

• This filing reflects routine RSU vesting and an open‑market sale. The RSU entries are not purchases — they document issuance on vesting (no out‑of‑pocket exercise cost). The withholding of shares to cover taxes is a common administrative step and does not itself indicate a buy/sell decision. The notable item for investors is the sizeable open‑market sale (12,500 shares ≈ $609k).
