Attention Capital Ledger: See where your attention actually goes

I built Attention Capital Ledger around a simple problem: most productivity systems track what you completed, but not whether the things consuming your attention were actually worth that attention. The idea was to treat attention more like capital. Instead of another to-do list, you log where your focus goes, classify each activity by its cognitive value, record the time it consumed, and define what needs to change. The second part of the system turns that data into an attention-yield dashboard so you can see the balance between high-leverage work and the activities quietly draining your day. I deliberately kept it lightweight: it runs locally in the browser, requires no account or subscription, and is designed to be used rather than maintained. This is part of a larger set of execution systems I'm building under Nexus Peak Digital, and I'd genuinely like feedback on this approach: when you think about a wasted day, is lack of time usually the problem—or where your attention went?
