You are rebuilding Manga Panel Generator as a legitimate native macOS desktop app while preserving the current product behavior and website delivery flow.

Source package contents:
- Windows desktop source: MangaPanelGeneratorWin/
- Website source: manga-panel-generator-site/
- Cloudflare config: wrangler.toml

What must remain true:
- The manga panel generation behavior must stay aligned with the current Windows app and browser build.
- Users must be able to generate page layouts, drag local images into specific panels, keep images clipped to their panel, pan and zoom only within the selected panel, and export clean PNG, JPEG, PDF, or print output.
- The app must remain clean and professional. No fake or mislabeled macOS deliverable.
- The website must be updated alongside the app so the macOS download and source/handoff links are accurate.

What to build:
1. Create a real macOS desktop app, not a browser bundle.
2. Choose a native host approach suitable for macOS, such as Swift/SwiftUI/AppKit with WKWebView if that is the fastest reliable path.
3. Reuse the existing web panel generator logic where practical, but replace all Windows-specific host functionality with native macOS equivalents.
4. Implement export for PNG, JPEG, PDF, and print using native macOS capabilities.
5. Implement robust local drag-and-drop from Finder into the app and into the target panel.
6. Rebuild the optional AI drawer in a stable macOS-friendly way if feasible. If not, disable it temporarily rather than shipping a broken drawer.
7. Update the website files so the macOS download is honest and clearly labeled.
8. Build, run, verify, and leave a working final build artifact plus the updated site source.

Important honesty requirement:
- If something is not truly native or not fully working, do not label it as complete. Fix it or label it accurately.

Please inspect the existing source first, then implement the macOS version end to end, including the website updates and deployment-ready source changes.
