Andy1292-tower/Forge-Planner ? reverse-engineered prompt

Build me a browser based planner for a crafting and mining game economy.

I want to enter recipe costs, craft times, line caps, mining income, and the items I am trying to make, then have the app figure out the best plan it can within a time limit. It should support multiple outputs at once, saved output sets, project planning with shopping lists, and a manual mode where I can assign each line by hand. The results should clearly show when something is impossible, when the search only found a best guess, and when a small shortfall is allowed.

Please make it feel like a real tool, with autosave in the browser, import and export, recovery for bad saves, and a clean preview of the plan and step by step guidance when a schedule is valid. Also include a simple way to report an issue, and a refresh notice when a new version is available. If you need current docs for any browser or build details, look them up online.
