Context

• This was a routine vesting of RSUs rather than an open‑market purchase or sale. The withholding of shares to satisfy tax obligations is standard practice (a cashless/withholding settlement), not a market sale intended as a liquidity or investment signal. The filing appears to have been made within the normal reporting timeframe.
