Can I vibecode SaneBox?

Build a comprehensive personal email triage and productivity application inspired by SaneBox.
Use exactly this stack: Next.js + React + TypeScript + Tailwind CSS for the frontend, and Node.js + Express + SQLite for a local backend, or an equivalent modern full-stack framework.
Primary job: Build an AI-assisted email companion that connects to a user's email account via IMAP and intelligently sorts incoming emails to reduce inbox clutter and improve focus.

Core Features to Implement:
1. IMAP Integration: Securely connect to an email account (Gmail, Outlook, etc.) using IMAP. Download headers and snippets to analyze messages without compromising full email body privacy if possible.
2. Intelligent Sorting Algorithm (SaneLater): Implement a system that analyzes incoming emails based on sender history, read rates, and user interactions. Automatically move emails deemed "less important" (e.g., newsletters, promotions, cold outreach) into a dedicated "@SaneLater" folder, keeping the primary inbox strictly for high-priority communications.
3. The Black Hole (SaneBlackHole): Create a feature where dragging an email into a specific "@SaneBlackHole" folder automatically creates a rule to send all future emails from that sender straight to the trash, acting as an instant unsubscribe mechanism.
4. Daily Digest: Generate a daily summary email or dashboard view of all messages routed to the "@SaneLater" folder, allowing the user to quickly scan and rescue any miscategorized emails.
5. Email Snoozing (SaneSnooze): Allow users to temporarily move non-urgent emails out of the inbox to a snooze folder, automatically returning them to the top of the inbox at a designated future time (e.g., tomorrow morning, next week).
6. Follow-up Reminders (SaneNoReplies): Track sent emails and create a dashboard or folder of emails that have not received a reply within a specified timeframe, reminding the user to follow up.
7. Attachment Management: Optionally, extract large attachments and save them to a local folder or simulated cloud storage, replacing them in the email with a link to save space.

Technical Requirements:
- Start from an empty folder and create the complete, working project.
- Make the application run locally, prioritizing privacy and security. Store user data and IMAP credentials securely in a local SQLite database or encrypted file.
- Do not add analytics, telemetry, ads, or third-party tracking.
- Put every secret and external credential in .env and provide .env.example.
- Build a polished, modern, and responsive user interface with clear navigation between Inbox, SaneLater, BlackHole, Snoozed, and Settings.
- Include robust error handling for IMAP connection issues, with clear loading and validation states.
- Ensure the app provides a degraded but functional mode if advanced AI sorting is unavailable, falling back to simple rules-based filtering based on sender email addresses.
- Write focused unit tests for the email sorting logic and IMAP connection handling.
- Create a comprehensive README detailing local setup, required environment variables, IMAP configuration steps, and architectural decisions.
- Include scripts for installation, development, and building the application.
- Prioritize a smooth onboarding experience where the user connects their IMAP account and sets up initial routing rules.
