That order matters. Once a task is written into a plan, it can begin to feel owed, even if the plan was built without considering meetings, caregiving, travel, interruptions, or the need to recover.
Choosing Tight, Balanced, or Open creates a boundary before enthusiasm fills the page. The choice is not a forecast of your worth or motivation. It is a practical estimate of how much room is available for deliberate commitments.
Your calendar can provide evidence: total open time, uninterrupted blocks, and fragmentation. But it cannot see everything. A day that looks open may still contain demanding work or life circumstances. That is why Steady suggests and you decide.
The capacity is a planning aid, not a locked door. If you add beyond it, the app makes that an explicit choice instead of letting extra work arrive invisibly.
