It helps compare the price of an item with lifespan, usage, depreciation, and retained value.\n\nThe core workflow turns purchase assumptions into cost per use, cost per hour, cost per week, cost per month, and value retained.\n\n## What it changes\n\nThe useful shift is from \"can I afford this?\" to \"will I actually use this enough for it to make sense?\"\n\n## Current status\n\nBuilding. The prototype covers the main comparison model and needs more reliability before it becomes a repeated-use tool."}
