Can I vibecode Sendspark?

Build a robust, self-hosted personalized video recording and sharing platform inspired by Sendspark. The goal is to allow users to record themselves or their screen and automatically generate personalized landing pages for outreach without needing expensive SaaS subscriptions.
Use Tauri 2, React, TypeScript, ffmpeg, and SQLite.

### Data Model & Schema
Design a local SQLite schema:
- `users`: id, name, company, email.
- `videos`: id, title, localFilePath, duration, createdAt, posterFramePath, transcript (text).
- `landing_pages`: id, videoId, urlSlug, ctaText, ctaUrl, customBackgroundColor, logoPath.
- `prospects`: id, name, company, email, customNote.
- `personalizations`: id, videoId, prospectId, personalizedThumbnailPath, status (pending, generated).

### Screens and UX Patterns
1. **Desktop Recorder Overlay**: A lightweight floating Tauri window showing the camera feed, a recording timer, pause/stop buttons, and a screen region selector.
2. **Library Dashboard**: A grid view of recorded videos with options to 'Trim', 'Create Landing Page', or 'Share'.
3. **Trim & Edit View**: A non-destructive video editor. Uses a timeline UI where users can drag handles to crop the start/end, and add simple text callouts.
4. **Landing Page Builder**: A form to configure how the video looks when shared (background color, CTA button text/link, logo). Shows a live preview.
5. **Personalization Engine**: A view to select a video and a list of prospects. The system generates unique links and thumbnails with the prospect's name overlaid on the video poster frame.

### Step-by-Step User Journeys
1. **Record**: User clicks the tray icon, selects "Screen + Cam", and records a 2-minute product demo.
2. **Edit & Trim**: User stops the recording, the main app window opens. They trim the first 5 seconds of dead air. The app uses local ffmpeg to process the trim and generate a poster frame.
3. **Configure Page**: User sets the CTA to "Book a Meeting" linking to their calendar.
4. **Share**: User clicks "Copy Link". The video and HTML landing page are exported to a designated local folder, which can be synced via a tool like Dropbox, or they can use the "reveal in folder" action to host it themselves.

### Technical Specifics
- Use Tauri for the desktop integration (tray icon, global shortcuts, screen capture APIs).
- Render video edits locally through ffmpeg with sensible H.264 and WebM presets.
- Do NOT implement public cloud hosting, viewer identity tracking, or engagement analytics (clicks/views). Keep all data local.
- Put secrets (if any external integrations are added later) in `.env` and ship `.env.example`.
- Generate a poster frame, transcript (via local whisper if possible, or placeholder), and Markdown summary beside each video.
- Include clear empty, loading, success, and recoverable error states.
- Provide a README with setup, architecture, and exact build commands.
- Write focused tests for the core video transformation flow.
