- Reported transaction: 4,191 shares withheld (code F) at $0.00; not an open‑market sale.

Context
This is a routine tax‑withholding/net‑settlement of vested RSUs (cashless/net settlement) and should not be interpreted as an active open‑market sale or a change in trading sentiment. It reduces the number of shares delivered from the award to cover taxes rather than generating proceeds for the insider.
