Can I vibecode Mailbird?

Build a modern Windows desktop email client inspired by Mailbird.
Use Tauri 2, React, TypeScript, TailwindCSS, SQLite for local storage, and standard IMAP/SMTP protocols.

### Data Model
- `Account`: id, email_address, imap_host, imap_port, smtp_host, smtp_port, is_oauth, auth_token (stored securely), color_code.
- `Folder`: id, account_id, name, type (inbox, sent, archive, trash, custom), unread_count.
- `Message`: id, folder_id, subject, snippet, from_address, to_address, date_received, is_read, has_attachments, html_body.
- `Attachment`: id, message_id, filename, mime_type, size, local_path.
- `Integration`: id, name (slack, whatsapp, calendar), icon, web_url, is_active.

### Screens & UX Patterns
1. **Unified Inbox Main View**: Three-pane layout. Leftmost sidebar: App icons (Mail + Integrations like WhatsApp/Calendar) and Accounts/Folders. Middle pane: Message list sorted by date with a quick search bar at the top. Right pane: Email reading view with inline reply.
2. **Compose Window**: A sleek, modal-style floating window or a dedicated tab for drafting emails, supporting rich text formatting, file attachments (drag-and-drop), and a send button with a "Send Later" option.
3. **Settings & Account Setup**: A wizard interface to add IMAP/SMTP details or authenticate via OAuth2 (Gmail/Outlook).
4. **App Integrations Sidebar**: Clicking an integration (e.g., WhatsApp) in the leftmost sidebar opens a web view of that service in the main area, allowing context switching without leaving the app.

### Step-by-Step User Journey
1. **Onboarding**: User launches the app and adds their Gmail and Outlook accounts via OAuth2. 
2. **Syncing**: The app syncs headers in the background via IMAP, displaying a progress indicator. The Unified Inbox populates with emails from both accounts.
3. **Reading & Searching**: User searches for "invoice". The local SQLite database is queried to return instant results. User clicks an email to read it; HTML content is sanitized and rendered.
4. **Replying**: User clicks "Reply", typing a response in the inline editor, and attaches a PDF.
5. **Sending**: User hits "Send". The app connects to the respective account's SMTP server to send the email and saves a copy to the local "Sent" folder.

### Technical Specifics
- Use standard IMAP library (via Tauri's Rust backend) to connect to mail servers.
- Store credentials using the OS keychain via Tauri plugins.
- Render HTML emails safely using a sandboxed `iframe` or a sanitized HTML renderer to prevent XSS.
- Implement an aggressive background sync strategy to cache headers in SQLite for instantaneous search and offline availability.
- Allow users to enable a "Unified Inbox" mode that merges messages from multiple `Account` entities, sorted by `date_received`.
