Can I vibecode Fathom HQ?

Build a comprehensive local web application to serve as a powerful financial analysis and management reporting dashboard, effectively replacing Fathom HQ for a small-to-medium business. The application should run locally using Node.js, Express, and SQLite (via better-sqlite3) to guarantee that all sensitive financial data remains completely private and never touches an external server. The front-end should be a responsive, modern dashboard built with React and styled with Tailwind CSS, utilizing a robust charting library like Recharts or Chart.js for data visualization.

The core data ingestion mechanism should allow me to drop standard CSV exports from accounting software (such as Xero or QuickBooks Online) into a designated local `./imports/` folder. The application must include a parser that automatically reads these Profit & Loss and Balance Sheet CSVs, sanitizes the data, and stores the monthly line items into the SQLite database.

Once the data is loaded, the application must compute and display an array of Key Performance Indicators (KPIs). Implement tracking for core financial metrics including revenue growth, gross profit margin, net profit margin, cash on hand, operating cash flow, and EBITDA. Provide a configuration file (e.g., `kpis.json`) that allows me to define custom KPIs using simple mathematical formulas based on my chart of accounts. For each KPI, I need the ability to set monthly or quarterly targets, and the dashboard should visually indicate performance (e.g., green/red indicators) against these benchmarks.

The dashboard UI must feature interactive KPI tiles showing month-over-month and year-over-year percentage changes. Below the tiles, provide 12-month trend charts for selected metrics. Crucially, I need a drill-down capability: clicking on a KPI or a chart data point should reveal a table detailing the underlying account balances that contributed to that figure for the specific period.

For management reporting, build a "Report Builder" view. This should allow me to assemble custom, professional-looking reports containing selected charts, KPI tables, and text blocks where I can manually add management commentary. Include a one-command script or a UI button that uses Puppeteer to render and export these assembled reports into highly polished PDF documents saved to a `./reports/` directory.

To approximate three-way cash flow forecasting without complex integrations, implement a simple scenario modeling tool. Allow me to input projected percentage changes for revenue and expenses for the upcoming 6-12 months, and project a rudimentary forward-looking P&L and Cash Flow statement based on historical trends from the imported data.

The entire system must be self-contained, requiring zero API keys, no user accounts, and no telemetry. Provide a comprehensive README explaining exactly which CSV formats are supported, how to structure the `kpis.json` file, and how to execute the PDF generation process.
