Context
A direct sale by an executive is often routine (for liquidity, diversification, or tax reasons) and does not by itself indicate a change in company outlook. Purchases typically carry more signal for bullish insider sentiment; this filing documents a routine open‑market disposition rather than an acquisition or option exercise.
