How much mental bandwidth do you actually have left today?

Burnout doesn't arrive with a warning. It accumulates as quiet drain — open loops you carry, interruptions you absorb, systems you've outsourced to your own memory, and rest that never quite restores. This is a small, honest calculator that gives you a single number for your reserve capacity, then shows you which leak to close first.

Nothing is saved. Nothing is sent. Just clarity, for you.
