Can I vibecode Expensify?

Build a powerful local-first expense management platform inspired by Expensify.
Stack: Next.js 15, TypeScript, Tailwind CSS, SQLite, and Drizzle ORM.

### Core Features to Implement:
1. **Smart Expense Tracking:**
   - Build an interface to log expenses manually or via CSV import.
   - Implement a receipt management system: upload receipt images (stored locally) and link them to expense entries.
   - Create a simulated "SmartScan" feature: a UI that lets users extract merchant, date, and amount from uploaded receipt images (using basic local heuristics or manual quick-entry forms).

2. **Distance & Mileage Tracking:**
   - Implement a mileage tracker where users can log trips.
   - Calculate reimbursements based on configurable custom or IRS mileage rates.

3. **Categorization & Policies:**
   - Implement automated rules for expense categorization based on merchant names.
   - Create mock "approval workflows" or policy flags (e.g., flag expenses over a certain amount or missing receipts).

4. **Reporting & Invoicing:**
   - Group expenses into comprehensive "Expense Reports".
   - Generate professional invoices or reimbursement summaries from these reports.
   - Provide a dashboard summarizing total spend, pending reimbursements, and category breakdowns.

### Technical Requirements:
- Ensure complete privacy: no analytics, telemetry, or third-party accounts.
- Store all data and receipt images locally.
- Implement a polished, accessible UI with smooth transitions and keyboard navigation.
- Provide comprehensive export functionality to prevent vendor lock-in.
- Deliberately exclude real AI parsing (unless using a local lightweight library), real corporate card issuing, and live accounting integrations.
- Provide a README with setup, architecture, and backup instructions.
