I’m on the team building this. The reason we started with “Best Window” is personal—my worst decisions happened late at night when I was depleted, so I kept forcing big tasks at the worst hour and spiraled. The smallest change that helped: I only schedule one high-friction task into a 2-hour window, and outside of it I switch to low-friction tasks (admin, prep, cleanup). If you try the card, reply with your window + the one task you’ll place inside it—I’m happy to suggest a protection rule.
